This PR introduces extensibility to the Fission CLI. The principle behind the design of this extensibility is taken from the approach git uses: the main binary (fission) calls other binaries (fission-workflows) - which it discovers using simple prefix-rules - based on specific commands (fission workflow <command>).

+# Multi-tenancy in Fission
+
+Multi-tenancy in Fission allows users to create Fission objects, i.e functions, packages, environments and triggers in different namespaces.
+It mandates that a function reference secrets, configmaps and its package (if explicity referenced during function creation/updation) to be present in the same namespace as the function.
+This allows user separation and prevents in-advertent access to sensitive data of other users sharing the same cluster.
+However, users are allowed and encouraged to share environments to ensure optimal utilization of cluster resources. To achieve this, users can create all the necessary environments in a ns, say ns1 and then go on to create functions in different namespaces and refer to env in ns1.
+Users that prefer complete isolation can create their env, functions in the same ns.  
+
+## Roles and privileges
+
+1. Cluster-Admin Role : Fission's services need cluster-admin privileges to monitor, create, update and delete resources across namespaces.
+2. Package-getter Role : This role has privileges to do a get, watch and list on fission package objects.
+3. Secret-Configmap-getter Role : This role has privileges to do a get, watch and list on secrets and configmaps.
+
+## Service Accounts 
+
+1. fission-fetcher
+
+This SA is created in every namespace that a user creates runtime environments in.
+Also created in function namespaces where a user creates functions that use NewDeploy executor backend.
+
+2. fission-builder
+
+This SA is created in every namespace that a user creates builder environments in.
+
+## Role-bindings
+
+1. Package-getter-binding
+
+Every time a user creates a package explicity in a namespace, this rolebinding is created in package's namespace (which is also function's namespace). This grants package-getter role to fission-fetcher SA present in the referenced environment's namespace.
+If the package is a source package, then, fission-builder SA present in the environment namespace is also added to this rolebinding.
+
+Next when the user creates a function in the same namespace, if the function's executor type is newdeploy, then, the fission-fetcher SA present in function namespace is also added to the same rolebinding.
+
+Note : For functions that have executor type poolmgr, the env pods are created in the namespace that env object is created. Whereas, for those functions that have executor type New deploy mgr, the function pods are created in the namespace that function object is created in.
+
+This is because, poolmgr allows env sharing and optimal resource utilization. so generic env pools are created in a different namespace and all functions that prefer sharing this env pool can reference these pools.
+If users require strict isolation, they can either create functions with new deploy backend, or, create env's in different namespaces and not share them across functions.
+
+2. Secret-Configmap-getter-binding
+
+Every time a user creates a function in a namespace, Secret-Configmap-getter-binding is created in the same namespace, granting secret-configmap-getter role to fission-fetcher SA present in the referenced environment's namespace in case the executor type is poolmgr.
+If the executor type is newdeploymgr, then the same rolebinding is created in the same namespace as the function, granting the same secret-configmap-getter role to fission-fetcher SA present in the function namespace.
+
+## Examples
+
+1. create a generic python runtime env in ns 1 and function with poolmgr executor type in ns 2 that references it.
+
+```bash
+$ fission env create --name python --image fission/python-env --envns ns1
+$ fission function create --name func1 --env python --code hello.py --fns ns2
+```
+
+2. create a builder and runtime environment in ns3, a source pkg in ns3 and a function referring to this src pkg also in ns3. (for complete isolation, all objs are in ns3)
+
+```bash
+$ fission env create --name python-builder-env --builder fission/python-builder --image fission/python-env --ns3
+$ fission package create --src src-pkg.zip --env python-builder-env --buildcmd "./build.sh" --pkgns ns3
+$ fission fn create --name func3 --fns ns3 --pkg $pkg --entrypoint "user.main"
+```
+
+## Note
+
+1. To maintain backward compatibility, fission objects that are created without the ns flags are created in default namespace. Also, the run time env pods in such a case will continue to live in fission-function ns and builder env pods in fission-builder ns
+2. Since all envs in a namespace have the same fission-fetcher SA mounted in them, even though multiple envs are created in a namespace and referenced by functions in different namespaces, the SA will have previleges to view those function's secrets if any.
+3. Similarly, if there are multiple functions in different namespaces but all sharing an env in one namespace, the fission-fetcher SA in that namespace will have previleges to see all of their secrets.

+# Fission CLI Extensibility
+
+### Approach
+To sum up the approach: git-style plugins.
+
+Plugins are named with the fission prefix `fission-*`. When fission is invoked with an undefined/non-core subcommand 
+is called (like `fission foo`). Fission will look in the PATH  
+
+**Installing Fission**
+```bash
+# The same as before
+$ curl -Lo fission https://github.com/fission/fission/releases/download/0.7.2/fission-cli-osx && chmod +x fission && sudo mv fission /usr/local/bin/
+```
+
+**Installing Fission Workflows**
+```bash
+# The same process as Fission cli itself
+$ curl -Lo fission https://github.com/fission/fission-workflows/releases/download/0.4.0/fission-workflows-osx && chmod +x fission-workflows && sudo mv fission-workflows /usr/local/bin/
+```
+
+**Invoking Fission Workflows**
+```bash
+$ fission workflows invocation get b1278e802a
+# Which is equivalent to:
+$ fission-workflows invocation get b1278e802a
+```
+General flow: 
+1. fission does not recognize `workflows` subcommand
+2. fission checks the path for a binary called `fission-workflows`
+3. fission finds the binary.
+4. fission invokes the `fission-workflows`, passing the remainder of the arguments.
+
+**Discoverability: fission --help**
+```bash
+$ fission --help
+USAGE:
+   fission [global options] command [command options] [arguments...]
+
+VERSION:
+   0.6.0

+   --help, -h      show help
+   --version, -v   print the version
+```
+Of course Fission needs to be able to find all plugins for this. There are several ways in which we can provide discoverability. The simplest one is for Fission to look in the path for all binaries starting with the `fission-*` prefix. Optionally, fission could invoke a specific command on the subcommand to get info about the plugin (such as version, help text, aliases...)
+
+With Fission Workflows this info would look something like this: 
+```bash
+$ fission-workflows --plugin
+name: workflows
+version: 0.4.0
+help: Inspect and manage workflow executions
+```
+The idea is that this plugin info is all completely optional. 
+If it is not available, we simply degrade the results to user. 
+This way users/we can easily prototype or add plugins without having to worry about adhering to some interface.
+
+**List version**
+```bash
+$ fission --version
+client: 
+  fission: 0.8.0
+  fission-workflows: 0.4.0
+server:
+  fission: 0.8.1
+  fission-workflows: 0.3.0
+```
+Again, versioning info for fission-workflows is taken from the plugin info of the commands. 
+Note: a related issue is to have some more formalized plugin support/discoverability on the server-side, 
+but that is out of the scope of this issue.
+
+### Other (optional) extensions and notes
+- Like git we could setup a preferred binary path, where fission looks first when searching for the subcommand. 
+This could optionally be defined with a `FISSION_EXEC_PATH`.
+- With the current approach we cannot have aliases for commands---fission will not be able to find fission-workflows 
+when the user calls `fission wf`. This might be UX issue, with these long path names. One option is let the user fix 
+it themselves by symlinking `fission-wf` to `fission-workflows`; using the plugin info Fission can recognize and 
+merge aliases together.
+- To help detect versioning conflicts (old version of fission, too new version of fission workflows). We could add 
+a `requires` field to the fission-workflows plugin info. Then we could throw a warning or error, when two out of sync 
+versions are being used. 
+- To avoid unhelpful errors to the user when they have not installed a plugin, we could add a heuristic to check 
+`https://github.com/fission/SUBCOMMAND` to see if the subcommand might be an uninstalled plugin. 
+OR, we could lookup a simple text file that contains common plugins `https://github.com/fission/fission/plugins.txt` 
+and list them as suggestions to the user. OR we could of course just default to a bit help text that says something 
+like `unknown subcommand 'foo'. If this is a plugin, ensure that it is present on your PATH`.
+
+---
+
+### Motivation
+
+The proposed approach is to use the git-based plugin system for now. Reasons for this approach over a sophisticated, 
+integrated plugin-based approach:
+- It is low effort to implement.
+- It is easy to extend with minimal to no required interface.
+- The binaries remain standalone, allowing users to separate them if needed and make independent development on the 
+binaries easy.
+
+Limitations of the proposed approach:
+- The user still has to do some work, adding binaries to the PATH; ensuring that permissions are correct; ensuring 
+that the binary is executable; how to deal with duplicate binaries on the PATH. All this makes this approach assume 
+basic/intermediate knowledge of the OS from the user.
+- I have to admit: I am not entirely sure if this approach requires any changes for Windows. Probably not.
+- Upgrading fission with many plugins could be cumbersome, as you would need to upgrade each binary one by one. 
+Improving this is probably best left to future work.
+
+
+The more heavyweight solution solves some of these limitations to an extent, but these do not way up to the increased 
+development and maintainance cost IMO. If needed we could explore this option (or some hybrid option) in the future.

+# Java Environment : Design & considerations
+
+This document documents the design and thoughts that lead to design of Java environment. Before we dive deeper, some important points:
+
+- When we say Java, we really mean JVM. That does not mean that all languages will work seamlessly, so support will be added gradually based on validation. Some of popular languages as of today are:
+    - Scala
+    - Groovy
+    - Kotlin (Server side with Spring)
+
+- In Java there are a few prominent frameworks which have a ecosystem of their own (See list below). How these framework fit in the environment will be detailed later, but it is important to understand their place in ecosystem and design for it.
+    - A large percentage of entertprise developers use [Spring framework](https://spring.io/) as has been shown by multiple surveys
+    - Reactive has taken up recently with data intensive operations [Reactive extensions for JVM](https://github.com/ReactiveX/RxJava)
+    - [Spark](http://sparkjava.com/) is a micro web framework
+
+A draft implementation of the Java environment design is in the branch [java_env_alpha](https://github.com/fission/fission/tree/java_env_alpha). Also a earlier implementation based on Vort.x framework [can be found here](https://github.com/tobias/fission-java-env/)
+
+## Function interface
+
+The goal is here is to minimize the lock in for the user into any framework as much as possible. Java 8 introduced an interface called ```Function``` which could be a great fit here. The user has to implement the ```Function<T, R>``` class and to meet the contract implement the apply method:
+
+```
+public class HelloWorld implements Function<T, R> {
+
+	public R apply(T str) {
+
+```
+
+Now - the T & R could be different things and we discuss some options below:
+
+### Body in request and response
+
+From the early implementation in the branch mentioned above, the environment extracts the body and send it as a JSON string. The JSON then can be transformed into the appropriate object by the function.
+
+This works well, but has one major limitation: the function does not get access to other things like headers etc. The same thing applies to the reponse: function can send the body but looses control over status code etc.
+
+### HttpServletRequest and HttpServletResponse
+
+It is possible to send the [HttpServeletRequest](https://docs.oracle.com/javaee/6/api/javax/servlet/http/HttpServletRequest.html) request object as it is to the function class but then the interface becomes a bit too low level. For example the function user has to retrieve the body of request using ```getInputStream``` which gives raw input stream and needs additional work. 
+
+Also most enterprise applications today use a framework of some sort for web applications instead of dealing with the raw HttpServlet
+
+### Custom/Context Object
+
+A custom object which encapsulates all needed fields etc. can be used to pass the data from environment to the function. But this means the user has to import a Fission object/library for this object in the application code.
+
+This approach has been taken in the implementation done earlier for a Java environment in Fission and [object interface can be found here](https://github.com/tobias/fission-java-env/blob/master/src/main/java/io/fission/api/Context.java). Related discussion is in the [issue](https://github.com/fission/fission/issues/91)
+
+AWS Lambda also uses a context object, but the purpose is very different, [details of context object here](https://docs.aws.amazon.com/lambda/latest/dg/java-context-object.html).
+
+### Spring's HttpEntity
+
+If we have to depend on a class/library, it is probably better to depend on a class which is part of ecosystem. So instead of using the low level interface of Servlet, we can use [HttpEntity's subclasses RequestEntity and ResponseEntity](https://docs.spring.io/spring/docs/5.0.5.RELEASE/javadoc-api/org/springframework/http/HttpEntity.html). This ensures that the function user is not locked in the Fission object contract, but also gets the full access to request/response object.
+
+The Spring cloud function project also discusses the issue of not having access to other things in request and [related issues are here](https://github.com/spring-cloud/spring-cloud-function/issues?utf8=%E2%9C%93&q=is%3Aissue+is%3Aopen+header)
+
+### Thoughts
+
+- If we only intend to pass request/response object to function - then using HttpEntity might be a good choice
+
+- If there is a need for additional exchange of information between the environment and function execution in future, then a custom/context object is a better option. We can wrap the HttpEntity's fields and additional fields in the custom context object
+
+## Environment Design
+
+JVM environment design is based on Spring boot and Spring MVC frameworks. The details can be found in branch, but here are some key points:
+
+- All classes in the function and dependent classes are loaded into JVM. Which means the user should supply the uber/fat jar for execution.
+- The entrypoint class is specified by the user as ```entrypoint``` flag on the class. The method is by convention (```apply``` as per the Function interface contract)

+The environment runs on an alpine image with some additional utility commandline tools installed, such as 'grep'. 
+However, in case you want to make use of more esoteric commandline tools, you should add the relevant apk to the 
 Dockerfile and build a new binary environment. See 'Compiling' for instructions.
 
 When executing functions using binaries, **ensure that the executable is built for the right architecture**. 
 Using the default binary environment this means that the binary should be build for Linux.
 
 ## Usage
+To get started with the latest binary environment:
+
+```bash
+fission env create --name binary --image fission/binary-env --builder fission/binary-builder
+```
+
 The interface to the executable used by this environment is somewhat similar to a [CGI interface](https://en.wikipedia.org/wiki/Common_Gateway_Interface).
 This means that any HTTP headers are converted to environment variables of the form "HTTP_<header-name>". For example these
 are some of frequently occurring headers:
 
-```
+```bash

 The body of HTTP piped over the STDIN to the executable. 
 All output that is provided to the server over the STDOUT will be transformed into the HTTP response.

+# Fission: Java and JVM Environment
+
+This is the JVM environment for Fission.
+
+It's a Docker image containing a OpenJDK8 runtime, along with a
+dynamic loader.  A few dependencies are included in the
+pom.xml file.
+
+## Customizing this image
+
+To add package dependencies, edit pom.xml to add what you
+need, and rebuild this image (instructions below).
+
+## Rebuilding and pushing the image
+
+You'll need access to a Docker registry to push the image: you can
+sign up for Docker hub at hub.docker.com, or use registries from
+gcr.io, quay.io, etc.  Let's assume you're using a docker hub account
+called USER.  Build and push the image to the the registry:
+
+```
+   docker build -t USER/jvm-env . && docker push USER/jvm-env
+```
+
+## Using the image in fission
+
+You can add this customized image to fission with "fission env
+create":
+
+```
+   fission env create --name jvm --image USER/jvm-env
+```
+
+Or, if you already have an environment, you can update its image:
+
+```
+   fission env update --name jvm --image USER/jvm-env   
+```
+
+After this, fission functions that have the env parameter set to the
+same environment name as this command will use this environment.
+
+## Web Server Framework
+
+JVM environment uses Tomcat HTTP server by default as it is included in spring web. You can choose to use jetty or undertow by changing the dependency in pom.xml file as shown below.
+
+```
+<dependency>
+	<groupId>org.springframework.boot</groupId>
+	<artifactId>spring-boot-starter-web</artifactId>
+	<exclusions>
+		<!-- Exclude the Tomcat dependency -->
+		<exclusion>
+			<groupId>org.springframework.boot</groupId>
+			<artifactId>spring-boot-starter-tomcat</artifactId>
+		</exclusion>
+	</exclusions>
+</dependency>
+<!-- Use Jetty instead -->
+<dependency>
+	<groupId>org.springframework.boot</groupId>
+	<artifactId>spring-boot-starter-jetty</artifactId>
+</dependency>
+```
+
+## Java and JVM builder
+
+JVM environment builder is based on OpenJDK8 and Maven 3.5.4 version. The default build command runs `mvn clean package` and uses the target/*with-dependencies.jar file for function. The default build command can be overridden as long as the uber jar file is copied to ${DEPLOY_PKG}.

+## Web Server Framework
+
+Python environment build and start a WSGI server, to support high HTTP 
+traffic. As it is applied in different use cases, this provides two server
+frameworks: `bjoern` and `gevent`. They all support high concurrency request.
+
+`bjoern` has good performance on RPS, to be ideal for most light resource 
+utilization cases.
+
+`gevent` is a good supplement because of its internal multi-threads. It 
+supports heavy resource load functions, with well distribution of response 
+time.
+
+Python environment pod remains `bjoern` framework by default. And it runs `gevent` 
+framework by setting the container environment `WSGI_FRAMEWORK` value to `GEVENT`. 
+
+The environment value is configured normally in two ways. One way is to set in Dockerfile 
+and build it into image. The other way is to set in Kubernetes deployment spec during 
+pod running and restart it.

+# Go example projects
+
+This repository contains a collection of Go programs and libraries that
+demonstrate the language, standard libraries, and tools.
+
+## The examples
+
+### [hello](hello/) ([godoc](//godoc.org/github.com/golang/example/hello)) and [stringutil](stringutil/) ([godoc](//godoc.org/github.com/golang/example/stringutil))
+
+    go get github.com/golang/example/hello
+
+A trivial "Hello, world" program that uses a stringutil package.
+
+Command [hello](hello/) covers:
+
+* The basic form of an executable command
+* Importing packages (from the standard library and the local repository)
+* Printing strings ([fmt](//golang.org/pkg/fmt/))
+
+Library [stringutil](stringutil/) covers:
+
+* The basic form of a library
+* Conversion between string and []rune
+* Table-driven unit tests ([testing](//golang.org/pkg/testing/))
+
+### [outyet](outyet/) ([godoc](//godoc.org/github.com/golang/example/outyet))
+
+    go get github.com/golang/example/outyet
+
+A web server that answers the question: "Is Go 1.x out yet?"
+
+Topics covered:
+
+* Command-line flags ([flag](//golang.org/pkg/flag/))
+* Web servers ([net/http](//golang.org/pkg/net/http/))
+* HTML Templates ([html/template](//golang.org/pkg/html/template/))
+* Logging ([log](//golang.org/pkg/log/))
+* Long-running background processes
+* Synchronizing data access between goroutines ([sync](//golang.org/pkg/sync/))
+* Exporting server state for monitoring ([expvar](//golang.org/pkg/expvar/))
+* Unit and integration tests ([testing](//golang.org/pkg/testing/))
+* Dependency injection
+* Time ([time](//golang.org/pkg/time/))
+
+### [appengine-hello](appengine-hello/) ([godoc](//godoc.org/github.com/golang/example/appengine-hello))
+
+	goapp get github.com/golang/example/appengine-hello
+
+A trivial "Hello, world" App Engine application intended to be used as the
+starting point for your own code.
+
+_Note_: The `goapp` tool is part of the [Google App Engine SDK for Go](https://cloud.google.com/appengine/downloads#Google_App_Engine_SDK_for_Go).
+
+### [gotypes](gotypes/) ([godoc](//godoc.org/github.com/golang/example/gotypes))
+
+The `go/types` package is a type-checker for Go programs. It is one of the most
+complex packages in Go's standard library, so we have provided this tutorial to
+help you find your bearings. It comes with several example programs that you
+can obtain using `go get` and play with as you learn to build tools that analyze
+or manipulate Go programs.
+
+### [template](template/) ([godoc](//godoc.org/github.com/golang/example/template))
+
+A trivial web server that demonstrates the use of the
+[`template` package](https://golang.org/pkg/text/template/)'s `block` feature.

+This code is a starting point for your Google App Engine application in
+Go.
+
+To run the application locally you need the install the [Go Cloud
+SDK](https://cloud.google.com/appengine/docs/go/#Go_tools) and execute the next
+command from the directory containing this file:
+
+    $ goapp serve app.yaml
+
+To deploy the application you have to first create an App Engine project
+and use it as the application file in all the yaml files.
