add resource prefix to multiple items w/ same kind
**Release note**:
```release-note
release-note-none
```
This patch ensures that a resource prefix is added to multiple items of
the same kind, when using `kubectl get all`. Before, a prefix was added only
when a single item was returned on `kubectl get all`, but ignored if only a
single resource kind existed but multiple items for that kind were
returned.
**Example**
```
$ kubectl get all
No resources found.
$ kubectl create service loadbalancer testsvc1 --tcp=8080
$ kubectl get all
NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE
svc/testsvc1 172.30.119.220 172.46.100.155,172.46.100.155 8080/TCP 1h
$ kubectl create service loadbalancer testsvc2 --tcp=8081
$ kubectl get all
NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE
svc/testsvc1 172.30.119.220 172.46.100.155,172.46.100.155 8080/TCP 1h
svc/testsvc2 172.30.241.197 172.46.164.158,172.46.164.158 8081/TCP 1h
```

RESTMapping method can now rely on RESTMappings by passing versions parameter and taking the first match found by RESTMappings method. In addition
a UT that test the new method has been added.
The only change in logic to what was before is when calling RESTMapping
we search all defaultGroupVersion as opposed to just one when no mapping was found for provided versions.
This patch ensures that a resource prefix is added to multiple items of
the same kind, when using `oc get all`. Before, a prefix was added only
when a single item was returned on `oc get all`, but ignored if only a
single resource kind existed but multiple items for that kind were
returned.

Fix kubectl Stratigic Merge Patch compatibility
As @smarterclayton pointed out in [comment1](https://github.com/kubernetes/kubernetes/pull/35647#pullrequestreview-8290820) and [comment2](https://github.com/kubernetes/kubernetes/pull/35647#pullrequestreview-8290847) in PR #35647,
we cannot assume the API servers publish version and they shares the same version.
This PR removes all the calls of GetServerSupportedSMPatchVersion().
Change the behavior of `apply` and `edit` to:
Retrying with the old patch version, if the new version fails.
Default other usage of SMPatch to the new version, since they don't update list of primitives.

clean up client version negotiation to handle no legacy API
Version negotiation fails if the legacy API endpoint isn't available.
This tightens up the negotiation interface based to more clearly express what each stage is doing and what the constraints on negotiation are. This is needed to speak to generic API servers.

Verify and update client-go staging area for every PR
We need to keep the staging area up-to-date to prevent PRs from breaking client-go.
It's marked as "WIP" because we need to decide the [versioning strategy](https://github.com/kubernetes/client-go/issues/9) for client-go first. This PR contains breaking changes for client-go.
This is blocking #29934 and potentially #34441
