Mayastor is unrecoverable if etcd cluster is broken

[peppepetra]

Summary

If etcd cluster is broken, mayastor is unrecoverable since etcd is deployed without using Persistent Volumes and not part of a StatefulSet as required by Mayastor basic architecture [0]

This means that everything using mayastor is lost and needs to be redeployed.
