In output of "kubeadm init", there are two strings for meaning of
bootstrap token which are "bootstraptoken" and "bootstrap-token".
This changes `[bootstraptoken]` to `[bootstrap-token]`.
The kubelet allows you to set `--pod-infra-container-image`
(also called `PodSandboxImage` in the kubelet config),
which can be a custom location to the "pause" image in the case
of Docker. Other CRIs are not supported.
Set the CLI flag for the Docker case in flags.go using
WriteKubeletDynamicEnvFile().
- 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 follows the pattern `kubectl` uses for logging.
There are two remaining glog.Infof call that cannot be removed easily.
One glog call comes from kubelet validation which calls features.SetFromMap.
The other comes from test/e2e during kernel validation.

As of 1.8.0 kubelet in kubeadm configuration ships with enabled feature
of node certificate autorotation, it makes sense to enable automatic
certificate rotation csr signing. It will help to avoid issues like
described in #53231 and #53237.
