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.
