[Storwize] update rccg name to metadata for clone-group-volumes

[Venkata krishna Thumu]

While creating a group either from source_group or group_snapshot, the resulted group-volumes metadata is not updated with the rccg_name attribute. This is happening due to the order of some function calls to update volume metadata.
Providing a fix to update rccg_name property to volume metadata which could cover all the possible cases like add a volume to the group, create a group from source_group and create a group from group_snapshot.
