mon/PGMonitor: always send pg creations after mapping

At some point in the dumpling cycle I separated the map stage from the
send stage.  We can send the creates any time we have a non-zero osdmap
epoch, and are in good shape as long as we do the map step after the
osdmap is loaded (hence the post_paxos_update).

Some background:

We originally introduced the map-but-don't send in a2fe0137, at which
point all was well because we only called it on ceph-mon startup.

Later, this turned into post_paxos_update in e635c478, at which point
it was now called by a running monitor.. but we didn't add in the
send_pg_creates().  This is where this bug stems from.

This particular path is responsible for the stalled test referenced in
bug #6673.

upstart, sysvinit: use ceph-crush-location hook

Instead of hard-coding a check in ceph.conf and some reasonable
defaults, defer this work to ceph-crush-location, and allow users to
specify their own hook with alternative logic.

This can be helpful in a nubmer of cases, like:

 - rack (or other) information included in hostname and easily parsed
   out by a hook
 - multiple types of devices in each host, resulting in 'parallel'
   crush trees (e.g., one for hdd, one for ssd)
