The kubectl command output suggests a user find more information at the
github source repo, eg:
$ kubectl --help
kubectl controls the Kubernetes cluster manager.
Find more information at https://github.com/kubernetes/kubernetes.
But there is curated user documentation available at, eg:
https://kubernetes.io/docs/reference/kubectl/overview/
which upon referencing yields a much better experience for a user than the
top of the source repo.
Fixes#56511

We shouldn't upgrade etcd without first warning the user that some etcd
version transitions can't be undone. We don't know what version the user
currently has, so we require either an explicit version and image, or an
interactive acknowledgement of this caveat.
This is modeled after the STORAGE_MEDIA_TYPE prompt just above.

Update cadvisor godeps to v0.28.3
**What this PR does / why we need it**:
Adds timeout around docker queries, to prevent wedging kubelet on node status updates if docker is non-responsive.
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes#53207
**Special notes for your reviewer**:
Kubelet's node status update queries cadvisor, which had no timeout on underlying docker queries. As a result, if docker was non responsive, kubelet would never be able to recover itself without a restart.
**Release note**:
```release-note
Timeout docker queries to prevent node going NotReady indefinitely.
```

remove time waiting after create storage account (save 25s)
**What this PR does / why we need it**:
I found azure cloud provider will always sleep 25 seconds after creating a new azure storage account:
https://github.com/kubernetes/kubernetes/blob/master/pkg/cloudprovider/providers/azure/azure_blobDiskController.go#L531
Actually it's not necessary now, since it's already using sync way to create a storage account:
https://github.com/kubernetes/kubernetes/blob/master/pkg/cloudprovider/providers/azure/azure_blobDiskController.go#L531
Above code will wait until the storage account is created in azure.
