Alyson Rosa 1f96b386b3 Netapp ONTAP: Add support to revert to snapshot

This patch adds support to revert to snapshot for NFS, FC and
iSCSI drivers with FlexVol pool.

Adds a method on client_cmode to rename a NFS volume file using
the file-rename-file zapi call.

The revert steps are:
  1. Create a clone volume file/LUN from snapshot.
  2. Change the original volume file/LUN path to a temporary path.
  3. Change clone file/LUN path to the original path.
  4. Delete the volume file/LUN on temporary path.

If any step fails, the original volume file/LUN is preserved and
the clone file/LUN is deleted.

For NFS, ONTAP clone file is not supported on FlexGroup pool, in
this case the generic implementation will perform the revert to
snapshot.

     NetApp ONTAP driver: Added support to Revert to Snapshot for the iSCSI, FC
     and NFS drivers with FlexVol pool. This feature does not support FlexGroups
     and is limited to revert only to the most recent snapshot of a given
     Cinder volume.
