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.
RunCmd uses Go's os/exec library to run commands directly. Since these
are not run through a shell, we can't use shell syntax for piping for
file redirection. The proper way to do that is to create a Command
object and set the Std{in,out,err} pipes appropriately. Luckily sed
can handle the behavior we need without having to manually set this up.

Unable to detach the vSphere volume from Powered off node
With the existing implementation when a vSphere node is powered off, the node is not deleted by the node controller and is in "NotReady" state. Following the approach similar to GCE as mentioned here - https://github.com/kubernetes/kubernetes/issues/46442.
I observe the following issues:
- The pods on the powered off node are not **instantaneously** created on the other available node. Only after 5 minutes timeout, the pods will be created on other available nodes with the volume attached to it. This means an application downtime of around 5 minutes which is not good at all.
- The volume on the powered off node are not detached at all when the pod with the volume is already moved to other available node. Hence any attempt to restart the powered off node will fail as the same volume is attached to other node which is present on this powered off node. (Please note that the volumes are not automatically detached from powered off in vSphere as opposed to GCE, AWS where volume is automatically detached from when node is powered off).
So inorder to resolve this problem, we have decided to back with the approach where the powered off node will be removed by the Node controller. So the above 2 problems will be resolved as follows:
- Since the node is deleted, the pod on the powered off node becomes instantaneously available on other available nodes with the volume attached to the new nodes. Hence there is no application downtime at all.
- After a period of 6 minutes (timeout period), the volumes are automatically detached from the powered off node. Hence any restarts after 6 minutes on the powered off node would work and not cause any problems as volumes are already detached.
For now, we would want to go ahead with deleting the node from node controller when a node is powered off in vCenter until we have a better approach. I think the best possible solution would be to introduce power handler in volume controller to see if the node is powered off before we can take any appropriate for attach/detach operations.

Do not GC exited containers in running pods
This fixes a regression introduced by #45896, and was identified by #52462.
This bug causes the kubelet to garbage collect exited containers in a running pod.
This manifests in strange and confusing state when viewing the cluster. For example, it can show running pods as having no init container (see #52462), if that container has exited and been removed.
This PR solves this problem by only removing containers and sandboxes from terminated pods.
The important line change is:
` if cgc.podDeletionProvider.IsPodDeleted(podUID) || evictNonDeletedPods {` --->
`if cgc.podStateProvider.IsPodDeleted(podUID) || (cgc.podStateProvider.IsPodTerminated(podUID) && evictTerminatedPods) {`

Endpoints can add a get or connect options type in their group
optionsExternalVersion is being used for shared types (meta.k8s.io). The
installer should first look in the current API group for GET and CONNECT
options objects before checking in `v1`.
OpenShift hit this while registering a new connect handler endpoint in an api group for an api that is aggregated. OpenShift should not be registering its API types into the core API group.

- Added more logs to help debug future failures
- Poll metrics a few additional times before failing the test
