The name of the parameter `mon osd down out subtree limit`
was incorrect (with `downout` instead of `down out`).
Furthermore, the description seemed to me a little bit
ambiguous.

There is a typo in document "Monitoring OSDs and PGs" as below
An OSD was ``down``, was restared, and is now ``recovering``.
This patch corrects 'restared' to 'restarted'. The whole code base
is also searched to ensure there is no more 'restared'.

doc/rados/operations/add-or-rm-mons: simplify the steps to add a mon

this change removes the step to "ceph mon add" before starting a new
monitor. because the existing leader will start an election at seeing
the MMonJoin message sent by the new joiner, after the quorum is
archieved, the monmap will be updated with the new monitor.
so, "ceph mon add" is not necessary to add a new monitor.
moreover, this command will be blocked until a new quorum is formed,
and the proposed monmap is accepted. but in case of adding a monitor
to a single monitor cluster, the leader will wait until at least two
of the monitors reply to it. apparently, this does not happen unless
the new monitor starts. so from the user's point of view, this
command hangs until timesout, if he/she does not start the mon.b
beforehand. but this is an expected behaviour.
so, to avoid this confusion and simplify the steps to add a new
monitor. we'd better simply remove this "ceph mon add" step.

Wip writeback throttling for cache tiering
This patch is to do write back throttling for cache tiering, which is similar to what the Linux kernel does for page cache write back. A paramter 'cache_target_dirty_high_ratio' (default 0.6) is introduced as the high speed flushing threshold, while leave the 'cache_target_dirty_ratio' (default 0.4) to represent the low speed threshold. The flush speed is controlled by limiting the parallelism of flushing. The maximum parallelism under low speed is half of the parallelism under high speed. If there is at least one PG such that the dirty ratio beyond the high threshold, full speed mode is entered; If there is no PG such that dirty ratio beyond the low threshold, idle mode is entered; In other cases, slow speed mode is entered.

Prior to this commit, the Network Configuration Reference guide and
Troubleshooting guide recommended opening a number of ports that were
unique to the number of daemons that we ran.
This doesn't really cover all use cases. Users can easily restart
daemons in ways that cause the daemons to bind to higher ports. This
leads to OSDs or MDSs binding to ports that are firewalled.
Update the Network Configuration Reference guide and Troubleshooting
guides to simply recommend that users open all the ports between 6800
and 7300 on their OSDs and MDSs.
