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 kubectl generic commands work with unstructured objects
part of making apply, edit, label, annotate, and patch work with third party resources
fixes#35149fixes#34413
prereq of:
https://github.com/kubernetes/kubernetes/issues/35496https://github.com/kubernetes/kubernetes/pull/40096
related to:
https://github.com/kubernetes/kubernetes/issues/39906https://github.com/kubernetes/kubernetes/issues/40119
kubectl is currently decoding any resource it doesn't have compiled-in to a ThirdPartyResourceData struct, which means it computes patches using that struct, and would try to send a ThirdPartyResourceData object to the API server when running `apply`
This PR removes the behavior that decodes unknown objects into ThirdPartyResourceData structs internally, and fixes up the following generic commands to work with unstructured objects
- [x] apply
- [x] decode into runtime.Unstructured objects
- [x] successfully use `--record` with unregistered objects
- [x] patch
- [x] decode into runtime.Unstructured objects
- [x] successfully use `--record` with unregistered objects
- [x] describe
- [x] decode into runtime.Unstructured objects
- [x] implement generic describer
- [x] fix other generic kubectl commands to work with unstructured objects
- [x] label
- [x] annotate
follow-ups for pre-existing issues:
- [ ] `explain` doesn't work with unregistered resources
- [ ] remove special casing of federation group in clientset lookups, etc
- [ ] `patch`
- [ ] doesn't honor output formats when persisting to server (`kubectl patch -f svc.json --type merge -p '{}' -o json` doesn't output json)
- [ ] --local throws exception (`kubectl patch -f svc.json --type merge -p '{}' --local`)
- [ ] `apply`
- [ ] fall back to generic JSON patch computation if no go struct is registered for the target GVK (e.g. https://github.com/kubernetes/kubernetes/pull/40096)
- [ ] ensure subkey deletion works in CreateThreeWayJSONMergePatch
- [ ] ensure type stomping works in CreateThreeWayJSONMergePatch
- [ ] lots of tests for generic json patch computation
- [ ] prevent generic apply patch computation among different versions
- [ ] reconcile treatment of nulls with https://github.com/kubernetes/kubernetes/pull/35496
- [ ] `edit`
- [ ] decode into runtime.Unstructured objects
- [ ] fall back to generic JSON patch computation if no go struct is registered for the target GVK

Revert "Add the ability to edit fields within a config map."
Fixes#40396
This reverts commit 31eca372c9.
#38445 broke edit for all resources other than configmaps:
```
$ kubectl edit serviceaccount default
Error from server (NotFound): configmaps "serviceaccount" not found
```
also, `edit` is a generic command, we can't add subcommands that claim the `configmap` space and mess with the things resourcebuilder accepts

Allows kubectl create -f to filter by selector.
From #32544.
The underlying `seletor` infrastructrue was implemented by #32599. The test is basically copy-paste of the corresponding test for `kubectl apply -f -l`.
```release-note
kubectl create now accepts the label selector flag for filtering objects to create
```

make client-go tools/auth and tools/clientcmd authoritative
These moved easily. Pure mechanical. I'll have a couple snip pulls for some of the more complicated packages. `pkg/util/homedir` was a transitive that moved with. It was only used in `kubectl` and you'd need it to be consistent with `clientcmd` loading order.

Add the ability to edit fields within a config map.
Addresses part of https://github.com/kubernetes/kubernetes/issues/36222
Example command:
```console
$ kubectl edit configmap foo --config-map-data=bar
```
Will open the data element named `bar` in the `ConfigMap` named `foo` in `$EDITOR`, the edited contents are then updated back to the config map.
@kubernetes/sig-cli
```release-note
Add a special purpose tool for editing individual fields in a ConfigMap with kubectl
```
