Move pkg/apimachinery/test to apimachinery

for circular dependency reason, all the test file contain both `"k8s.io/apimachinery/pkg/apis/meta/v1"` and `"k8s.io/apimachinery/pkg/runtime"` is hard to move to a ideal location, so I create a separated test package for those files
I also bump the example package :https://github.com/kubernetes/kubernetes/tree/master/staging/src/k8s.io/apiserver/pkg/apis/example here for apimachinery, @sttts told me it's ok if to bump file if only for test EDIT: seems it's no need to bump, will update soon

Allow NetworkPolicy.spec updates

flush conntrack for udp service when # of backend changes from 0
fixes: #48370
Allows the proxier to be used on an interface that's not the default route,
otherwise hostIP gets set to the default route interface even if that's
not what the user intended.
If listen IP isn't given, falls back to previous behavior.
Volume mounting logic introduced in #43775 and #45623 checks
for subPath existence before attempting to create a directory,
should subPath not be present.
This breaks if subPath is a dangling symlink, os.Stat returns
"do not exist" status, yet `os.MkdirAll` can't create directory
as symlink is present at the given path.
This patch makes existence check to use os.Lstat which works for
normal files/directories as well as doesn't not attempt to follow
symlink, therefore it's "do not exist" status is more reliable when
making a decision whether to create directory or not.
subPath symlinks can be dangling in situations where kubelet is
running in a container itself with access to docker socket, such
as CoreOS's kubelet-wrapper script

Provide a way to setup the limit NO files for rkt Pods
**What this PR does / why we need it**:
This PR allows to customize the Systemd unit files for rkt pods.
We start with the `systemd-unit-option.rkt.kubernetes.io/LimitNOFILE` to allows to run workloads like etcd, ES in kubernetes with rkt.
**Special notes for your reviewer**:
Once again, I followed @yifan-gu guidelines.
I made a basic check over the values given inside the `systemd-unit-option.rkt.kubernetes.io/LimitNOFILE` (integer and > 0).
If this check fails: I simply ignore the field.
The other implementation would be to fail the whole SetUpPod.
We discussed using a key like `rkt.kubernetes.io/systemd-unit-option/LimitNOFILE` but the validation only allows a single `/` in this field:
```The Deployment "tiller" is invalid: spec.template.annotations: Invalid value: "rkt.kubernetes.io/systemd-unit-option/LimitNOFILE": a qualified name must consist of alphanumeric characters, '-', '_' or '.', and must start and end with an alphanumeric character (e.g. 'MyName', or 'my.name', or '123-abc', regex used for validation is '([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9]') with an optional DNS subdomain prefix and '/' (e.g. 'example.com/MyName')```

OpenAPI downloads protobuf rather than Json
**What this PR does / why we need it**:
The current implementation of the OpenAPI getter fetches the swagger in a Json format from the apiserver. The Json file is big (~1.7mb), which means that it takes a long time to download, and then a long time to parse. Because that is going to be needed on each `kubectl` run later, we want this to be as fast as possible.
The apiserver has been modified to be able to return a protobuf version of the swagger, which this patch intends to use.
Note that there is currently no piece of code that exists that allows us to go from the protobuf version of the file, back into Json and/or `spec.Swagger`. Because the protobuf is not very different (but significantly different enough that it can't be translated), I've updated the code to use `openapi_v2.Document` (the protobuf type) everywhere rather than `spec.Swagger`. The behavior should be identical though.
There are more changes that are coming in follow-up pull-requests: using the gzip version (also provided by the new apiserver) to even further reduce the size of the downloaded content, and use the HTTP Etag cache mechanism to completely get rid of recurrent fetch requests. I'm currently working on these two features.

fixes to two pkg/util unit tests
Spun out from #46537. Trivial unit test fixes:
- `pkg/util/ebtables/ebtables_test.go`'s tests are incorrectly named and so weren't getting run by "go test". (And one of them had a typo in it so it failed after the name was fixed)
- In `pkg/util/iptables/iptables_test.go`, the deletion tests were apparently written by copying+pasting+editing the creation tests, but they forgot to change the names of the tests to match the behavior that was being tested in the new version

deletePod handler in the deployment controller shouldn't set owner refs
**What this PR does / why we need it**:
This PR stops the deletePod handler in the deployment controller from adopting replica sets when determining if a deployment needs to be requeued. It leaves this logic to the replication loop, removing the replica set adoption side effect.

Fix Unstructured field accessor
Fix the Unstructured GetDeletionGracePeriodSeconds accessor which was
always returning nil regardless of the underlying stored value. The
field value always appearing nil prevents Custom Resource instances
from being deleted when garbage collection is enabled for CRs and
when DeletePropagationOrphan is used. More generally, this fix means that
delete-on-update now works for CR instances.
Add some test coverage for Unstructured metadata deserialization.
The Unstructured DeletionGracePeriodSeconds field marshals as a value
type from JSON and as a pointer type via SetDeletionGracePeriodSeconds.
The GetDeletionGracePeriodSeconds method now supports handling both
int64 and *int64 values so that either underlying value can be returned.
Add a reflection-based unit test which attempts to exercise all the
Object Get/Set methods for nil handling.
```release-note
Registries backed by the generic Store's `Update` implementation support delete-on-update, which allows resources to be automatically deleted during an update provided:
* Garbage collection is enabled for the Store
* The resource being updated has no finalizers
* The resource being updated has a non-nil DeletionGracePeriodSeconds equal to 0
With this fix, Custom Resource instances now also support delete-on-update behavior under the same circumstances.

kubectl: 'apply view-last-applied' must not use printf() semantics
**What this PR does / why we need it**:
This fixes `kubectl apply view-last-applied` to not use `fmt.Fprintf()`, as this will cause format codes in the YAML/JSON to be interpreted. For example, if a resource manifest contains `%r`, this would cause `view-last-applied` so print `%!r(MISSING)`.

**Special notes for your reviewer**:
**Release note**:
```release-note
Fixes an edge case where "kubectl apply view-last-applied" would emit garbage if the data contained Go format codes.
```

GPU support is ramping up and we do not have a lot of reviewers that
are familiar with the codebase. I added myself as a reviewer and
copied a few people from the kubelet OWNERS file as approvers.

cmd/create_deployment: refactor long function
Refactor the `createDeployment` function under `pkg/kubectl/cmd`.
- [x] Behavior has been extracted to two helper functions.
- [x] Behavior remains identical.
- [x] Logic has been made explicit through function naming and comments.
This is essentially the pattern I've been following in my larger branches (the ones that are pending the merge of #46468). Want to get some design feedback before I get too far away from `master`.
Thanks!
