mon/OSDMonitor: avoid potential expensive grace calculation

Resolved by choosing the move-to-top implementation. Removed unused vars.

mon/OSDMonitor: improve reweight_by_utilization() logic

By calling reweight_by_utilization() method, we are aiming at an evener result
of utilization among all osds. To achieve this, we shall decrease weights of
osds which are currently overloaded, and try to increase weights of osds which
are currently underloaded when it is possible.
However, we can't do this all at a time in order to avoid a massive pg migrations
between osds. Thus we introduce a max_osds limit to smooth the progress.

The problem here is that we have sorted the utilization of all osds in a descending
manner and we always try to decrease the weights of the most overloaded osds
since they are most likely to encounter a nearfull/full transition soon, but
we won't increase the weights from the most underloaded(least utilized by contrast)
at the same time, which I think is not quite reasonable.

Actually, the best thing would probably be to iterate over teh low and high osds
in parallel, and do the ones that are furthest from the average first.

(cherry picked from commit 1a07123c38e3fecb3fb2e43bbbae962d8411d287)

change:
            use NULL to replace the nullptr because we don't have C++11

osd: reset session->osdmap if session is not waiting for a map anymore

we should release the osdmap reference once we are done with it,
otherwise we might need to wait very long to update that reference with
a newer osdmap ref. this appears to be an OSDMap leak: it is held by an
quiet OSD::Session forever.

the osdmap is not reset in OSD::session_notify_pg_create(), because its
only caller is wake_pg_waiters(), which will call
dispatch_session_waiting() later. and dispatch_session_waiting() will
check the session->osdmap, and will also reset the osdmap if
session->waiting_for_pg.empty().

log: do not repeat errors to stderr

If we get an error writing to the log, log it only once to stderr.
This avoids generating, say, 72 GB of ENOSPC errors in
