Protect against nil panic in apply

**What this PR does / why we need it**: `kubectl apply` has a potential panic (actually verified in OpenShift in https://github.com/openshift/origin/issues/15017) where a `patcher` calls the `runDelete` function with a nil `resource.RESTClient`, but under some conditions the client is required by that function.

This patch add new storage class parameter called
`volumeoptions` which can be used to set various volume options.
for eg# if you want to enable encryption on volumes,
the values like `client.ssl on`, `server.ssl on`..etc can be passed
to `volumeoptions` parameter in storageclass.

Static deepcopy – phase 1

This PR is the follow-up of https://github.com/kubernetes/kubernetes/pull/36412, replacing the
dynamic reflection based deepcopy with static DeepCopy+DeepCopyInto methods on API types.

This PR **does not yet** include the code dropping the cloner from the scheme and all the
porting of the calls to scheme.Copy. This will be part of a follow-up "Phase 2" PR.

A couple of the commits will go in first:
- [x] audit: fix deepcopy registration  https://github.com/kubernetes/kubernetes/pull/48599
- [x] apimachinery+apiserver: separate test types in their own packages #48601 
- [x] client-go: remove TPR example #48604
- [x] apimachinery: remove unneeded GetObjectKind() impls #48608 
- [x] sanity check against origin, that OpenShift's types are fine for static deepcopy https://github.com/deads2k/origin/pull/34

TODO **after** review here:
- [x] merge https://github.com/kubernetes/gengo/pull/32 and update vendoring commit

make externalAdmissionHookConfigurationManager distinguish API disabled error

The externalAdmissionHookConfigurationManager does not return "DisabledErr" even if the API is disabled, so the GenericWebhook admission controller will not fail open.

The GenericWebhook admission controller is default to off, so the bug is hidden in most cases. To be safe, we should cherrypick it to 1.7.

```release-note
Fix a bug where the GenericWebhook admission plugin does not fail open when the admissionregistration API is disabled

- port direct calls to deepcopy funcs
- apimachinery: fix types in unstructured converter test
- federation: fix deepcopy registration

- add DeepCopyObject() to runtime.Object interface

Always use gcr.io/google_containers for side-loaded Docker images

**What this PR does / why we need it**: #45391 changed the behavior for what registry we use in the sideloaded docker images tarfiles shipped with releases. As a result of that change, if `KUBE_DOCKER_REGISTRY` is set to anything other than `gcr.io/google_containers`, clusters will fail to start on GCE (and other places where the side-loaded images are used).

This PR reverts that change in behavior, which I believe was unintentional; we'll always use `gcr.io/google_containers` for the docker image tarfiles, but will tag the images with `$KUBE_DOCKER_REGISTRY` if different.

Also, I'm fixing a small bug in variable names that I introduced in #47939.

Note that with recent changes here and in the release repo, we don't even need to tag with `KUBE_DOCKER_REGISTRY` and `KUBE_DOCKER_IMAGE_TAG`, but that's a more extensive change, and this smaller fix is more suitable for cherry-picking to 1.7.
