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.

Use metav1.*Options in genericapiserver
Treat DeleteOptions as unversioned in metainternalversion for decoding
of bodies from older clients. Use the metav1 Options structs from
generic api server and the appropriate codec.
Completes the move to using generic server side code for API objects

move the discovery and dynamic clients
Moved the dynamic client, discovery client, testing/core, and testing/cache to `client-go`. Dependencies on api groups we don't have generated clients for have dropped out, so federation, kubeadm, and imagepolicy.
