ApplyTo adds the admission chain to the server configuration the method lazily initializes a generic plugin
that is appended to the list of pluginInitializers.
apiserver.Config will hold an instance of SharedInformerFactory to ensure we only have once instance.
The field will be initialized in apisever.SecureServingOptions

Replace hand-written informers with generated ones
Replace existing uses of hand-written informers with generated ones.
Follow-up commits will switch the use of one-off informers to shared
informers.
This is a precursor to #40097. That PR will switch one-off informers to shared informers for the majority of the code base (but not quite all of it...).
NOTE: this does create a second set of shared informers in the kube-controller-manager. This will be resolved back down to a single factory once #40097 is reviewed and merged.
There are a couple of places where I expanded the # of caches we wait for in the calls to `WaitForCacheSync` - please pay attention to those. I also added in a commented-out wait in the attach/detach controller. If @kubernetes/sig-storage-pr-reviews is ok with enabling the waiting, I'll do it (I'll just need to tweak an integration test slightly).

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.

replace global registry in apimachinery with global registry in k8s.io/kubernetes
We'd like to remove all globals, but our immediate problem is that a shared registry between k8s.io/kubernetes and k8s.io/client-go doesn't work. Since client-go makes a copy, we can actually keep a global registry with other globals in pkg/api for now.

Rename "release_1_5" clientset to just "clientset"
We used to keep multiple releases in the main repo. Now that [client-go](https://github.com/kubernetes/client-go) does the versioning, there is no need to keep releases in the main repo. This PR renames the "release_1_5" clientset to just "clientset", clientset development will be done in this directory.

```release-note
The main repository does not keep multiple releases of clientsets anymore. Please find previous releases at https://github.com/kubernetes/client-go
