Subject: [PATCH] Ceph: wait for services to shutdown during cleanup

It can take ceph-osd and ceph-mon a few seconds to complete when
they are killed.  This races against the umount command in cleaup
and can often result in $CEPH_DATA_DIR failing to unmount since
it is still in use.

Wait for these processes to stop to ensure the mount point is
umounted successfully.
