qa: hang on waiting for clean; OSDs not joining cluster
See http://pulpito.ceph.com/teuthology-2015-10-23_23:08:01-kcephfs-master-testing-basic-multi/1122914/. I copied the OSD and monitor logs into that directory.
It looks like the OSD daemons are all running; I didn't establish why they aren't joining from one of the hosts. (I suppose it's vaguely possible something is broken on plana10, but I wouldn't count on it.)
