UPSTREAM: 44798: Cinder: Automatically Generate Zone if Availability …

…in Storage Class is not Configured Backport of Kubernetes PR #44798 (kubernetes/kubernetes#44798). In case the availability parameter is not configured in a cinder Storage Class the cinder volume is always provisioned in the nova availability zone. That is incorrect. Now, the cinder volume is provisioned in a zone that is generated by an algorithm from the set of zone available in the cluster. Positive side-effect: cinder volumes for individual pods in a StatefulSet are provisioned in unique zones. This increases the StatefulSet resilience.
