move api server no kube dep packages
Simple moves, see commit titles. I did not move the source of the generated swagger, I simply change the destination of the script. I'm ok building a little debt to complete the move.

add OWNERS for client-go
client-go is the source (not a copy) for the generic client libraries we wrote. This is a copy of the OWNERS file from `pkg/client`.

Use full package path for definition name in OpenAPI spec
We were using short package name (last part of package name) plus type name for OpenAPI spec definition name. That can result in duplicate names and make the spec invalid. To be sure we will always have unique names, we are going to use full package name as definition name. Also "x-kubernetes-tag" custom field is added to definitions to list Group/Version/Kind for the definitions that has it. This will help clients to discover definitions easier.
Lastly, we've added a reference from old definition names to the new ones to keep backward compatibilities. The list of old definitions will not be updated.
**Release note**:
- Rename OpenAPI definition names to type's full package names to prevent duplicates
- Create OpenAPI extension "x-kubernetes-group-version-kind" for definitions to store Group/Version/Kind
- Deprecate old definition names and create a reference to the new definitions. Old definitions will be removed in the next release.

propagate explicit nulls in apply
Rebase of https://github.com/kubernetes/kubernetes/pull/35496 on top of https://github.com/kubernetes/kubernetes/pull/40260
The client-side propagation of the raw value is no longer needed, since the client is preserving the original object in unstructured form (explicit nulls are preserved).
Kept tests and CreateThreeWayMergePatch changes from https://github.com/kubernetes/kubernetes/pull/35496
```release-note
kubectl apply now supports explicitly clearing values not present in the config by setting them to null
```
- [x] Clean up orphaned objects in test-cmd to preserve pre- and post- conditions
- [x] improve CreateThreeWayMergePatch test to not filter based on string comparison to test name

move client/record
An attempt at moving client/record to client-go. It's proving very stubborn and needs a lot manual intervention and near as I can tell, no one actually gets any benefit from the sink and source complexity it adds.

Preventing nil pointer reference in client_config
When a user tries to set the `extensions` map in the kube config, loading of the client config causes nil pointer exception because the `Context`, `Cluster`, `AuthInfo` objects are created without initializing the extensions map. This PR attempts to fix that.

genericapiserver: cut off more dependencies – episode 3
Compare commit subjects.
This is the first step to get `apiserver_test.go` and `watch_test.go` in `pkg/genericapiserver/endpoints` cutoff from k8s.io/kubernetes dependencies.
After this we have to sync client-go and then "episode 4" can go in.

Make HandleError prevent hot-loops
Add an error "handler" that just sleeps for a bit if errors happen more
often than 500ms. Manually tested against #39816. This doesn't fix#39816 but it does keep it from crippling a cluster.
```release-note
Prevent hotloops on error conditions, which could fill up the disk faster than log rotation can free space.
