ceph-daemons: restructured (but incomplete) init.d script

Only start/stop items explicitly defined in startup.conf.

Start specific osds or mdss (e.g. 'start osd12')

No NUM_OSD type iteration.. that only makes sense in a testing/dev
environment.

Extract options for each daemon in both start AND stop path, so that we can
stop the right daemon... e.g. if it is on a remote host or some such thing.

Try to be smart about looking for things in . or /usr/bin, /etc/ceph, etc.
