ceph-create-keys should not be started on boot of mons with systemd so should
not exist as 'After' or 'Wants' for the ceph-mon.service

This change introduces the following behaviour:
- When ceph-mon starts, it will try to start ceph-mgr with the same
instance id (Wants=), but will *not* fail to start if ceph-mgr
doesn't start (i.e. the mon still works as it always did).
- ceph-mgr will start After= ceph-mon, and will stop and start when
ceph-mon stops and starts, because it's PartOf= ceph-mon.
If you don't want ceph-mgr to run on the mons, you need to mask the
service, i.e. `systemctl mask ceph-mgr@INSTANCE`. Hostnames are
typically instance names, so `systemctl mask ceph-mgr@$(hostname)`
should suffice if you wish to disable ceph-mgr on the mons.

Currently, the systemd daemons are not restarted on failure. This patch
adds this functionality and sets the defaults to those defined in
upstart. This resolves to 3 fails per 30 minutes for osd, mon and mds
and 5 fails per 30 seconds for radosgw.

If systemd has task accounting enabled, a default of 512 tasks
will be applied to all systemd units.
For ceph, this is way to low even for a modest cluster, so stop
this restriction being applied and allow administrators to apply
limits using sysctl.

This change makes it so the mon/osd/mds/radosgw daemons:
o Cannot write to /usr, /etc, and /boot.
o Cannot access /home, /root, or /run/user.
o Each daemon gets its own private /tmp and /var/tmp.
o All daemons get a private /dev without physical devices (exception: osd)
I'm not sure if the osd daemon needs access to a full /dev so I left
ProtectDevices out for ceph-osd@.service.

We were observed to be hitting the limit on centos7
(triggering pthread_create failures) on a ~2000 OSD cluster.
Increasing this resolves it!

Allow all daemons drop privilege themselves, instead of letting
systemd do it.
Among other things, this means that admins can conditionally not
drop prives by setting
setuser match path = /var/lib/ceph/$type/$cluster-$id
in their ceph.conf to ease the pain of upgrade.

Before this patch, the command 'logrotate -f /etc/logrotate.d/ceph'
was generating an error "Failed to reload ceph.target: Job type reload is not
applicable for unit ceph.target".
Before we issue systemctl reload, check that there is at least
one active ceph-* service. (The hyphen is significant.)
Since we use grep, make the grep package a dependency.

Added ceph.target
Made ceph-mds, ceph-mon, ceph-osd services part of ceph.target
Made ceph-mds, ceph-mon, ceph-osd services require partitions to be available.
Added ceph init script with sysV like behaviour.

This patch adds systemd service files. It is possible to start and
enable multiple instances (per monid, osdid, mds name), e.g.
# systemctl start ceph-mon@node01
# systemctl enable ceph-mon@node01
# systemctl start ceph-osd@0
# systemctl enable ceph-osd@0
The ceph cluster can be set in the system config file:
/etc/sysconfig/ceph
adding or editing the CLUSTER environment variable.
