- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods

The service account authenticator isn't the only authenticator that
should respect API audience. The authentication config structure should
reflect that.

controller-manager: switch to options+config pattern and add https+auth
This PR switch the {kube,cloud}-controller-managers to use the Options+Config struct pattern for bootstrapping, as we use it throughout all apiservers. This allows us to easily plug in https and authn/z support.
Fixes parts of https://github.com/kubernetes/kubernetes/issues/59483
This is equivalent to https://github.com/kubernetes/kubernetes/pull/59408 after squashing.
```release-note
Deprecate insecure HTTP port of kube-controller-manager and cloud-controller-manager. Use `--secure-port` and `--bind-address` instead.

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.
