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.

remove unneeded storage options
Cleanup of some storage serialization options that only kube and federation api server (and maybe not even that one) need.
You may have called it a snip, but this moves the options out of generic entirely.

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.

Enable protobufs as storage format by default
**Release note**:
```release-note
Change default storage format to protobufs. With this PR apiserver will be writing objects serialized as protobufs to etcd. If the apiserver was upgraded in the existing clusters, until an object will be written, it will still be stored as JSON. Apiserver can deal with some data being in json and some in protobuf format as of 1.4 release.

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.

pkg/genericapiserver: re-add generic feature gates
https://github.com/kubernetes/kubernetes/pull/40543 removed the kubernetes feature gates (which subsume the generic ones) from genericapiserver. This PR readds the generic ones again.
This is not strictly necessary for kube-apiserver. But some other downstream project without its own feature gates needs this.
