Cleanup a TODO from godeps -> vendor change

This logs a false "error" message, so it's time to go.  It was needed to ensure
nobody has stale build images laying around, but that was quite a while ago, so
it's probably safe now.

Make validators return error strings

Part of the larger validation PR, broken out for easier review and merge.  Builds on previous PRs in the series.  This is a group of smaller commits, so I don't waster precious PR numbers.

Also treat 0.0.0.0 as special, like loopback and multicast.

Break deployment controller into separate self-contained files

Fixes https://github.com/kubernetes/kubernetes/issues/25867

* rolling.go (has all the logic for rolling deployments)
* recreate.go (has all the logic for recreate deployments)
* sync.go (has all the logic for getting and scaling replica sets)
* rollback.go (has all the logic for rolling back a deployment)
* util.go (contains all the utilities used throughout the controller)

Leave back at deployment_controller.go all the necessary bits for
creating, setting up, and running the controller loop.

Also add package documentation.

@kubernetes/deployment @mfojtik this is an honest refactoring of the controller. In the long term, I believe it will help a lot with maintainance.

Add links to issues referenced in some design documents

Add link to issues referenced in `nodeaffinity.md` and `podaffinity.md`. It would be helpful to visit the issue directly. Also fix broken format of `podaffinity.md` when # is at the beginning of a line.

The GNU `expr` command supports both the `expr match STRING REGEXP` and `expr STRING : REGEXP` command syntax.

The BSD `expr` command only has the `expr STRING : REGEXP` syntax.

Add a new container runtime interface

This PR includes a proposal and a Go file to re-define the container runtime interface.
This is based on the original doc: https://docs.google.com/document/d/1ietD5eavK0aTuMQTw6-21r67UU73_vqYSUIPFdA0J5Q/

The umbrella issues is #22964

Add additional testing scenarios for compute resource requests=0

I was asked about the qos tier of a pod that specified 

`--requests=cpu=0,memory=0 --limits=cpu=100m,memory=1Gi`

and in just investigating current behavior, realized we should have an explicit test case to ensure that 0 values are preserved in defaulting passes, and that this is still a burstable pod (but the lowest for that tier as it related to eviction)

/cc @vishh 

This commit includes a proposal and a Go file to re-define the container
runtime interface.

Note that this is an experimental interface and is expected to go through
multiple revisions once developers start implementing against it. As stated in
the proposal, there are also individual issues to carry discussions of
specific features.

Update "kubectl get all" to display resource type as part of name

fixes #23838
release-note-none

When running "kubectl get all", or printing any output with mixed resource kinds, an additional column is added to the output with each resource's kind:

`kubectl get all --all-namespaces`
