kubectl describe: show multiple labels/annotations on multiple lines
Small UX improvement: when there is more than one label/annotation, it's more readable to see them on the different lines.
Before:
```console
$ kubectl describe svc
Name: s2i-test
Namespace: test2
Labels: app=s2i-test,foo=bar
...
```
After:
```console
$ kubectl describe svc
Name: s2i-test
Namespace: test2
Labels: app=s2i-test
foo=bar
...
```
This change affects output of the labels/annotations in many of the sub-commands of the `kubectl describe`.

kubectl: more sophisticated pod selection for logs and attach
Trying to get the logs or attach to an object other than a pod
will poll forever if that object has no replicas. This commit adds
a 20s timeout for polling.

kubectl rolling-update support for same image
Fixes#23497.
Enables `kubectl rolling-update --image` to the same image, adding a `--image-pull-policy` flag to remove ambiguity. This allows rolling-update to behave as an "update and/or restart" (https://github.com/kubernetes/kubernetes/issues/23497#issuecomment-212349730), or as a forced update when the same tag can mean multiple versions (e.g. `:latest`). cc @janetkuo @nikhiljindal

Use tagged redis image for kubectl test, move json test file out of deprecated examples
Closes#24642
Changes the redis image to use the :e2e tagged version on gcr.io.
Since the examples/ subdir is deprecated in favor of the new kubernetes/kubernetes.github.io I just copied this file to test-manifests/kubectl like some other files.

Fix unintended change of Service.spec.ports[].nodePort during kubectl apply
Please refer #23551 for more detail. @bgrant0607 I think this simple fix should be ok to reuse nodePort. @thockin ptal.
Release note: Fix unintended change of `Service.spec.ports[].nodePort` during `kubectl apply`.

Cluster Verification Framework
I've spent the last few days looking at the general patterns of verification we have that we tend to reuse in the e2es. Basically, we need
- label filters
- forEach and WaitFor (where forEach doesn't necessarily waitFor anything).
- timeouts
- multiple phases (reusable definition of state)
- an extensible way to define cluster state that can evolve over time in a data object rather than as a set of parameters that have magic semantics
This PR
- implements the abstract above functionality declaratively, and w/o hidden semantics.
- addresses the sprawling duplicate methods in #23540, so that we can phase out the wrapper methods and replace them with well defined, extensible semantics for cluster state.
- fixes the recently discovered #23730 issue (where kubectl.go is relying on examples.go, which is obviously wacky) by using the new framework to implement forEachPod in just a couple of lines and migrating the wrapper function into framework.go.
There is some cleanup to do here, but this is seemingly working for a couple of use cases that are important (spark,cassandra,...,kubectl) tests. - i played with a few different ideas and this wound up seeming to be the most natural implementation from a usability standpoint...
in any case, just thought id push this up as a first iteration, open to feedback.

- rebase: ForEach only on Running pods
- add waitFor step in guestbook describe and wrapper
- simplify logs in polling, make panic immediate, give rolluped stats in
the logs.
Improve logging for failure on ForEach
Only close the stdout/stderr pipes from kubectl port-forward when we're truly done with the command,
instead of as soon as runPortForward exits.
Also try to gracefully stop kubectl port-forward via SIGINT, instead of always sending SIGKILL, as
this will help avoid spdy goroutine leaks in the Kubelet.
Update the Deployments' API types, defaulting code, conversions, helpers
and validation to use ReplicaSets instead of ReplicationControllers and
LabelSelector instead of map[string]string for selectors.
Also update the Deployment controller, registry, kubectl subcommands,
client listers package and e2e tests to use ReplicaSets and
LabelSelector for Deployments.
