    GlusterFS: Delete active snapshot file on volume delete.

    If a snapshot is taken of a volume that is attached to an active
    instance, the volume file used by the instance will be switched to
    the new snapshot file that is created. When you delete the
    snapshot, the base volume file will be merged with the snapshot
    file and the base volume is deleted. Upon a deleting the active
    volume, the active snapshot file is not deleted because it does not
    have the expected name that cinder is looking for, i.e.
    volume-<uuid>. Instead, the snapshot file has the name
    volume-<uuid>.<snapshot-uuid>. This patch looks at the volume info
    file to find any active snapshot file and properly delete it when
    the volume is deleted.
