Restore pv and pvc in mysql chart

This change restores the pv.yaml and pvc.yaml that were previously
removed.  These are required for the case when the NFS provisioner is
disabled.  I've added a condition to these files such that they should
be disabled if the NFS provisioner is enabled.  The two ways of
managing entities need to be mutually exclusive.
