ceph-conf: do not log

If you are querying the conf for an osd and it has a log configured, we
should not generate any log activity.

This isn't super pretty, but it is much less intrusive that wiring a 'do
not log' flag down into CephContext and a zillion other places.

ceph-conf: no admin_socket

We don't need to worry about pidfile because that is done by the fork
functions, which ceph-conf doesn't call.
