add lease endpoint reconciler
**What this PR does / why we need it**: Adds OpenShift's LeaseEndpointReconciler to register kube-apiserver endpoints within the storage registry.
Adds a command-line argument `alpha-endpoint-reconciler-type` to the kube-apiserver.
Defaults to the old MasterCount reconciler.

**Release note**:
```release-note
Adds a command-line argument to kube-apiserver called
--alpha-endpoint-reconciler-type=(master-count, lease, none) (default
"master-count"). The original reconciler is 'master-count'. The 'lease'
reconciler uses the storageapi and a TTL to keep alive an endpoint within the
`kube-apiserver-endpoint` storage namespace. The 'none' reconciler is a noop
reconciler that does not do anything. This is useful for self-hosted
environments.

move CRD behind TPR
Second attempt at https://github.com/kubernetes/kubernetes/pull/46297
@liggitt since @sttts is out can you take a look and hopefully find me a different, more sane way to do this? It's a little crazy, but I left a large comment explaining why I think its the only way.

allow fallthrough handling from go-restful routes
This sets up the gorestful routes to fall through to a default handler and reorders the API to be ahead of the other endpoints. This makes it possible to cleanly support cases of "match, fail, try this other handler" which we'll need for API server composition.

Promote TokenReview to v1
Peer to https://github.com/kubernetes/kubernetes/pull/40709
We have multiple features that depend on this API:
- [webhook authentication](https://kubernetes.io/docs/admin/authentication/#webhook-token-authentication)
- [kubelet delegated authentication](https://kubernetes.io/docs/admin/kubelet-authentication-authorization/#kubelet-authentication)
- add-on API server delegated authentication
The API has been in use since 1.3 in beta status (v1beta1) with negligible changes:
- Added a status field for reporting errors evaluating the token
This PR promotes the existing v1beta1 API to v1 with no changes
Because the API does not persist data (it is a query/response-style API), there are no data migration concerns.
This positions us to promote the features that depend on this API to stable in 1.7

```release-note
The authentication.k8s.io API group was promoted to v1

Remove non-generic options from genericapiserver.Config
Remove non-generic options from genericapiserver.Config. Changes the discovery CIDR/IP information to an interface and then demotes several fields.
I haven't pulled from them genericapiserver.Options, but that's a future option we have. Segregation as as a followup at the very least.

Switch DisruptionBudget api from bool to int allowed disruptions [only v1beta1]
Continuation of #34546. Apparently it there is some bug that prevents us from having 2 different incompatibile version of API in integration tests. So in this PR v1alpha1 is removed until testing infrastructure is fixed.
Base PR comment:
Currently there is a single bool in disruption budget api that denotes whether 1 pod can be deleted or not. Every time a pod is deleted the apiserver filps the bool to false and the disruptionbudget controller sets it to true if more deletions are allowed. This works but it is far from optimal when the user wants to delete multiple pods (for example, by decreasing replicaset size from 10000 to 8000).
This PR adds a new api version v1beta1 and changes bool to int which contains a number of pods that can be deleted at once.

Remove static kubelet client, refactor ConnectionInfoGetter
Follow up to https://github.com/kubernetes/kubernetes/pull/33718
* Collapses the multi-valued return to a `ConnectionInfo` struct
* Removes the "raw" connection info method and interface, since it was only used in a single non-test location (by the "real" connection info method)
* Disentangles the node REST object from being a ConnectionInfoProvider itself by extracting an implementation of ConnectionInfoProvider that takes a node (using a provided NodeGetter) and determines ConnectionInfo
* Plumbs the KubeletClientConfig to the point where we construct the helper object that combines the config and the node lookup. I anticipate adding a preference order for choosing an address type in https://github.com/kubernetes/kubernetes/pull/34259

fix pod eviction storage
Refactor pod eviction storage to remove the tight order coupling of the storage. This also gets us ready to deal with cases where API groups are not co-located on the same server, though the particular client being used would assume a proxy.
