Fission 1.6.0

When a function with executor type newdeploy got created, Newdeploy
is expected to create deployment/HPA/service for it and insert serviceEntry
to the cache for later use. Once clients call the function, newdeploy returns
the serviceEntry to the router.

However, the log shows that the newdeploy was unable to find the entry and
prints "Resource not found - key 'xxx' not found". The root cause is that the
informer controller instead of processing items in parallel, it dispatches XXFunc
to process items one by one. So if there is any problem during the creation of the
kubernetes resource, it takes a longer time to process the next item and hence
the serviceEntry was not inserted before clients call the function.

This PR lets the newdeploy to process items in extra goroutines instead of blocking
the process loop. It's a workaround to solve the problem above, we should consider
using workqueue to solve it in the future.

-
-Fission Concepts
-----------------
-
-A _function_ is a piece of code that follows the fission function
-interface.
-
-An _environment_ contains the language- and runtime-specific parts of
-running a function.  
-
-The following environments are currently available:
- 
- | Environment                          | Image                     |
- | ------------------------------------ | ------------------------- |
- | Binary (for executables or scripts)  | `fission/binary-env`      |
- | Go                                   | `fission/go-env`          |
- | JVM                                  | `fission/jvm-env`         |
- | .NET                                 | `fission/dotnet-env`      |
- | .NET 2.0                             | `fission/dotnet20-env`    |
- | NodeJS (Alpine)                      | `fission/node-env`        |
- | NodeJS (Debian)                      | `fission/node-env-debian` |
- | Perl                                 | `fission/perl-env`        |
- | PHP 7                                | `fission/php-env`         |
- | Python 3                             | `fission/python-env`      |
- | Ruby                                 | `fission/ruby-env`        |
-
-You can also extend environments or create entirely new
-ones if you want.  (An environment is essentially just a container
-with a webserver and dynamic loader.)
-
-A _trigger_ is something that maps an event to a function; Fission
-as of today supports [HTTP request](https://docs.fission.io/usage/trigger/#create-a-http-trigger), [timed](https://docs.fission.io/usage/trigger/#create-a-time-trigger), and [message queue](https://docs.fission.io/usage/trigger/#create-a-message-queue-trigger) triggers.
-
-Usage
------
-
-```bash
-
-  # Add the stock NodeJS env to your Fission deployment
-  $ fission env create --name nodejs --image fission/node-env
-
-  # A javascript one-liner that prints "hello world"
-  $ curl https://raw.githubusercontent.com/fission/fission/master/examples/nodejs/hello.js > hello.js
-
-  # Upload your function code to fission
-  $ fission function create --name hello --env nodejs --code hello.js
-
-  # Map GET /hello to your new function
-  $ fission route create --method GET --url /hello --function hello
-
-  # Run the function.  This takes about 100msec the first time.
-  $ fission function test --name hello
-  Hello, world!
-```
-

+# Fission: Tensorflow Serving Environment
+
+This is the Tensorflow Serving environment for Fission.
+
+It's a Docker image containing a Go runtime, along with a tensorflow serving service.
+
+## How it works
+
+Tensorflow Serving is an serving service that supports both RESTful API and gRPC endpoints. In current implementation,
+Go server launches `tensorflow_model_server` to load in model during specialization. As long as the Go server receives
+requests from router it creates a reverse proxy that connects to RESTful API endpoint exposed by tensorflow_model_server
+and get response from the upstream server for user.
+
+## Build this image
+
+```
+docker build -t USER/tensorflow-serving . && docker push USER/tensorflow-serving
+```
+
+## Using the image in fission
+
+You can add this customized image to fission with "fission env create":
+
+```
+fission env create --name tensorflow --image USER/tensorflow-serving --version 2
+```
+
+After this, fission functions that have the env parameter set to the
+same environment name as this command will use this environment.

-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.

-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify

-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.

-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.

-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-# 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.
