Purge removes logs, and we want to archive those, so explicitly shut down
all daemons before doing the archiving step.

Purge will uninstall and (in so doing) stop the daemons. This avoids trying
to tar up the mon data or logs while they are being written to, which
avoids errors like
2013-04-16T20:21:47.103 INFO:teuthology.task.ceph-deploy:Archiving mon data...
2013-04-16T20:21:47.545 INFO:teuthology.orchestra.run.err:tar: ./ceph-mira089/store.db/000009.log: file changed as we read it
Also drop the unnecessary uninstall (it is implied by purge).
