probeAttachedVolume improvement in Cinder
What this PR does / why we need it:
During OpenStack Cinder volume attachment, kubelet creates too many udev "change" events.
If volume attachement takes long, then udev event queue gets full,therefore
udev does not answer requests from docker, and makes Kubernetes node unhealthy.
This patch will extend the udevadm trigger period,
and use the udevadm settle to ensure that any device nodes
have been created successfully before proceeding.

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.

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.
