This contains a few different builder manager fixes:
* Update the zip file structure to avoid an extra subdirectory
* Annotate packages with what functions are using them
* Only trigger builds when there is no deployment archive
* Python environment loadpath bugfixes
* Other bugfixes
Switch Fission's storage over to the new CustomResourceDefinitions, from the deprecated ThirdPartyResources. This allows us to be compatible with Kubernets 1.8 and onwards.
This also adds a CLI tool for dumping state from an old fission version and restoring state into new CRDs.
The storage service is unaffected by this change.
closes#319
* Make default node-env use alpine, and support separate debian env. List envs in documentation.
* Copy ONBUILD base image commands into node Dockerfiles
* Copy more commands from onbuild image
* Tidy dockerfiles
Add a flag to the environment to control multiple specialization -- the max number of functions per container. This can be set to 1 or infinity.
Add an api proxy to workflow apiserver from the controller.
Add function metadata to FunctionLoadRequest; every v2 environment now knows which function it's loading (but can ignore that information if it wants to).
Add function identity headers to router. This is useful for multiple specialization, so the router can disambiguate between different function calls. (If this turns out to be a non-trivial perf overhead, we could add these headers conditionally, but for now they are always added.)
This change orchestrates function builds.
Environments (in v2) define a builder image, just like they do a runtime image. The builder image contains a build script that's invoked with source and deployment paths (as env vars).
The buildermgr watches for environments with build images defined, and creates build deployments and services.
Functions can define source and deployment. Buildermgr watches for functions with source code (and build status == pending) and invokes the environment's builder when appropriate. It captures logs from the build and sets the build status (success/failure) and build lots into the PackageStatus.
Since `mz` has already bumped for several times without
breaking change, it's better to follow the updates.
```console
$ npm outdated
Package Current Wanted Latest Location

```
Fixes: https://github.com/fission/fission/issues/167
This adds partial support for multiple specialization to the
function service cache. It allows Add() to succeed if the pod and
address maps already contain entries.
But it doesn't deal with DeletePod and TouchByAddress. That's ok for
now, because the workflow engine never deletes the environment pod
(that pod is the workflow engine).
However, if/when we want full support for multiple specialization,
that will require updating both DeletePod and TouchByAddress.
Allows dumping v0.1 state to a json file and restoring it into a new v0.2.1 fission installation.
