Ceph

Depends on #2404. Depends on branch chef-2. TODO merge not available currently.
Ensure osd data disks do NOT use GPT partitions with the ceph osd UUID
(4fbd7e29-9d25-41b8-afd0-062c0ceff05d) Use "gdisk /dev/sdb", "p", "i"
"1" etc to check, look at "Partition GUID code"; recreating the
partition should be enough.
Prepare ceph.conf with [osd.$id]host=xxx settings,
with osd_data, osd_journal and mon_data at default values.
mkfs and mount the osd data partitions using /etc/fstab to match osd_data etc default values.
Set up a cluster using mkcephfs.
Test all of "sudo service ceph start", "sudo /etc/init.d/ceph start", reboot.
PASS CRITERIA: upstart does not run ceph daemons ("sudo initctl
list|grep ceph" has only "stop" lines), sysvinit works as normal, ceph
cluster is healthy with all daemons participating.
DEV NOTE: The only reason upstart job ceph-mon-all doesn't run
ceph-mon is lack of "done" flags.
