Send events on certain service repair controller errors
**What this PR does / why we need it**:
This PR enables sending events when the api-server service IP and port allocator repair controllers find an error repairing a cluster ip or a port respectively.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#54303
**Special notes for your reviewer**:
In case of an error, events will be emitted [every 3 minutes](https://github.com/kubernetes/kubernetes/blob/master/pkg/master/controller.go#L93) for each failed Service. Even so, event spam protection has been merged (#47367) to mitigate the risk of excessive events.
**Release note**:
```release-note
api-server provides specific events when unable to repair a service cluster ip or node port
```

Added PreStopHooks to apiserver to allow clean shutdown.
BootStrapController now registers a PreStopHook to clean up the kubernetes service endpoints. The PreStopHooks allow the apiserver to shutdown cleanly under a controlled shutdown case. The BootStrapController's PreStopHook will clean up after itself by removing the apiserver from the list of IPs in the kubernetes service.

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.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixeskubernetes/community#939fixeskubernetes/kubernetes#22609
**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.
