glusterd: cleanup unneeded volumes after peer detach
Performs cleanup on the detached peer and in the cluster after a peer detach, and also adds a new check before starting detach. Cleanup - On the detached peer, cleanup removes the entries of those volumes on the peer that do not have all their bricks on it. This prevents these stale volumes from being added to a new cluster when peer is attached to one. In the cluster, all those volumes which have all their bricks on the detached peer are removed. Checks- Checks if all the peers in the cluster are online and connected, except the peer being detached, before starting detach. Using force will bypass this check and do detach.
