Add TPR to CRD migration helper.
This is a helper for migrating TPR data to CustomResource. It's rather hacky because it requires crossing apiserver boundaries, but doing it this way keeps the mess contained to the TPR code, which is scheduled for deletion anyway.
It's also not completely hands-free because making it resilient enough to be completely automated is too involved to be worth it for an alpha-to-beta migration, and would require investing significant effort to fix up soon-to-be-deleted TPR code. Instead, this feature will be documented as a best-effort helper whose results should be verified by hand.
The intended benefit of this over a totally manual process is that it should be possible to copy TPR data into a CRD without having to tear everything down in the middle. The process would look like this:
1. Upgrade to k8s 1.7. Nothing happens to your TPRs.
1. Create CRD with group/version and resource names that match the TPR. Still nothing happens to your TPRs, as the CRD is hidden by the overlapping TPR.
1. Delete the TPR. The TPR data is converted to CustomResource data, and the CRD begins serving at the same REST path.
Note that the old TPR data is left behind by this process, so watchers should not receive DELETE events. This also means the user can revert to the pre-migration state by recreating the TPR definition.

support NonResourceURL for kubectl create clusterrole
Release note:
```release-note
add --non-resource-url to kubectl create clusterrole
```
This change makes it so that errors during watch decoding panic the
server if it is in a test environment. This allows us to catch coder
errors related to storing incompatible types at the same location in
etcd.

kubectl: fix deprecation warning bug
**What this PR does / why we need it**:
Some kubectl commands were deprecated but would fail to print the
correct warning message when a flag was given before the command name.
# Correctly prints the warning that "resize" is deprecated and
# "scale" is now preferred.
kubectl resize [...]
# Should print the same warning but no warning is printed.
kubectl --v=1 resize [...]
This was due to a fragile check on os.Args[1].
This commit implements a new function deprecatedCmd() that is used to
construct new "passthrough" commands which are marked as deprecated and
hidden.
Note that there is an existing "filters" system that may be preferable
to the system created in this commit. I'm not sure why the "filters"
array was not used for all deprecated commands in the first place.
**Release note**:
```release-note
NONE

Command tree and exported env in kubectl plugins
This is part of `kubectl` plugins V1:
- Adds support to several env vars passing context information to the plugin. Plugins can make use of them to connect to the REST API, access global flags, get the path of the plugin caller (so that `kubectl` can be invoked) and so on. Exported env vars include
- `KUBECTL_PLUGINS_DESCRIPTOR_*`: the plugin descriptor fields
- `KUBECTL_PLUGINS_GLOBAL_FLAG_*`: one for each global flag, useful to access namespace, context, etc
- ~`KUBECTL_PLUGINS_REST_CLIENT_CONFIG_*`: one for most fields in `rest.Config` so that a REST client can be built.~
- `KUBECTL_PLUGINS_CALLER`: path to `kubectl`
- `KUBECTL_PLUGINS_CURRENT_NAMESPACE`: namespace in use
- Adds support for plugins as child of other plugins so that a tree of commands can be built (e.g. `kubectl myplugin list`, `kubectl myplugin add`, etc)
**Release note**:
```release-note
Added support to a hierarchy of kubectl plugins (a tree of plugins as children of other plugins).
Added exported env vars to kubectl plugins so that plugin developers have access to global flags, namespace, the plugin descriptor and the full path to the caller binary.

initial types for TPRs
This pull starts creating the types described by https://github.com/kubernetes/community/blob/master/contributors/design-proposals/thirdpartyresources.md . In the initial pull different names were suggested. I've started this pull with `CustomResource.apiextensions.k8s.io`.
The structure begins as a separate API server to facilitate rapid prototyping and experimentation, but the end result will be added to the end of the `kube-apiserver` chain as described in https://github.com/kubernetes/community/blob/master/sig-api-machinery/api-extensions-position-statement.md .
Because it is separate to start (not included in any default server), I don't think we need a perfect name, but I'd like to be close.

Move k8s.io/metrics to staging/
This is to break the cyclic dependency in our code base: kubernetes depends on k8s.io/metrics, which depends on kubernetes/staging/client-go.
@DirectXMan12 i actually moved it to staging because we will need the flexibility to update metrics code directly to do many planned refactors, so the copy of metrics in kubernetes has to be the source of truth.
client-gen is not enabled for the code yet, we can enable it after you port your changes to client-gen.
`make generated_files` is enabled for metrics.

redis-proxy is replaced with redis-master in test-cmd-util.sh, to

The redis-proxy pod in test/fixtures/doc-yaml/user-guide/multi-pod.yaml

test/e2e_node: prepull images with CRI
Part of https://github.com/kubernetes/kubernetes/issues/40739
- This PR builds on top of #40525 (and contains one commit from #40525)
- The second commit contains a tiny change in the `Makefile`.
- Third commit is a patch to be able to prepull images using the CRI (as opposed to run `docker` to pull images which doesn't make sense if you're using CRI most of the times)
Marked WIP till #40525 makes its way into master
@Random-Liu @lucab @yujuhong @mrunalp @rhatdan
Per Clayton's suggestion, move stuff from cluster/lib/util.sh to
hack/lib/util.sh. Also consolidate ensure-temp-dir and use the
hack/lib/util.sh implementation rather than cluster/common.sh.

add singular resource names to discovery
Adds the singular resource name to our resource for discovery. This is something we've discussed to remove our pseudo-pluralization library which is unreliable even for english and really has no hope of properly handling other languages or variations we can expect from TPRs and aggregated API servers.
This pull simply adds the information to discovery, it doesn't not re-wire any RESTMappers.

Cleanup make test-integration
``make test-integration`` was using the first positional arg passed to ``WHAT`` to filter the list of integration test packages. This PR switches to passing ``WHAT`` verbatim to be consistent with how ``make test`` works. That means the new way to scope execution to a single integration package will be:
```bash
make test-integration WHAT="./test/integration/auth" KUBE_TEST_ARGS="-run=^TestKindAuthorization$"
```
Instead of:
```bash
make test-integration WHAT="auth -test.run=^TestKindAuthorization$"
```
This PR also ensures that the script exits after running a single test case and that etcd cleanup is not done twice at the end of a successful test run. Both were issues encountered while diagnosing the scoping issue.

Updating kubectl to send delete requests with orphanDependents=false if --cascade is true
Ref https://github.com/kubernetes/kubernetes/issues/40568#38897
Updating kubectl to always set `DeleteOptions.orphanDependents=false` when deleting a resource with `--cascade=true`.
This is primarily for federation where we want to use server side cascading deletion.
Impact on kubernetes: kubectl will do another GET after sending a DELETE and wait till the resource is actually deleted. This can have an impact if the resource has a finalizer. kubectl will wait till the finalizer is removed and then the resource is deleted, which is the right thing to do but a notable change in behavior.

Add storage.k8s.io/v1 API
v1 API is direct copy of v1beta1 API. This v1 API gets installed and exposed in this PR, I tested that kubectl can create both v1beta1 and v1 StorageClass.
~~Rest of Kubernetes (controllers, examples,. tests, ...) still use v1beta1 API, I will update it when this PR gets merged as these changes would get lost among generated code.~~ Most parts use v1 API now, it would not compile / run tests without it.
**Release note**:
```
Kubernetes API storage.k8s.io for storage objects is now fully supported and is available as storage.k8s.io/v1. Beta version of the API storage.k8s.io/v1beta1 is still available in this release, however it will be removed in a future Kubernetes release.
Together with the API endpoint, StorageClass annotation "storageclass.beta.kubernetes.io/is-default-class" is deprecated and "storageclass.kubernetes.io/is-default-class" should be used instead to mark a default storage class. The beta annotation is still working in this release, however it won't be supported in the next one.
