- 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

This extends the Kubelet to create and periodically update leases in a
new kube-node-lease namespace. Based on [KEP-0009](https://github.com/kubernetes/community/blob/master/keps/sig-node/0009-node-heartbeat.md),
these leases can be used as a node health signal, and will allow us to
reduce the load caused by over-frequent node status reporting.
- add NodeLease feature gate
- add kube-node-lease system namespace for node leases
- add Kubelet option for lease duration
- add Kubelet-internal lease controller to create and update lease
- add e2e test for NodeLease feature
- modify node authorizer and node restriction admission controller
to allow Kubelets access to corresponding leases
Workaround for bug #59450.
Related to PR #59441.
Locally test runs about 90 seconds.
However on the bazel-test CI the test frequently runs over 5 minutes.
Extending the timeout as a work-around to ease the rerun problem.
As @mikedanese notes :-
The Validate calls to the vendored go-openapi library are which make the test slow:
https://github.com/kubernetes/kubernetes/blob/master/pkg/master/master_openapi_test.go#L91
We should probably do more perf and send a patch to upstream.
TestValidOpenAPISpec often takes over a minute. This bumps the timeout
from 60 seconds to 300 seconds. On my computer it takes ~73 seconds
consisently. The calls to Validate() take the majority of the time.

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.
