init-ceph: print trailing n in "status" output

init-ceph: print trailing n in "status" output

the version command is handled by HelpHook, which does not print newline
at the end of the returned JSON. so the output of "status" subcommand
looks like:

=== osd.1 ===
osd.1: running {"version":"Development"}=== osd.2 ===
osd.2: not running.

with this change, a newline is added to the end of version.

also use the "daemon" subcommand to talk to the asok, let the "ceph" cli
to figure out the asok path.
