f223ac9291 mon/PGMap: factor mon_osd_full_ratio into MAX AVAIL calc
If we only fill OSDs to 95%, we should factor that into
the MAX AVAIL calculation for the pool.

Signed-off-by: Bara Ancincova <bara@redhat.com>

https://bugzilla.redhat.com/show_bug.cgi?id=1368528

From email conversation with Sage and Sam:

I don't think it is used at all, and at a minimum it is
untested and undocumented and the implementation is alomst
certainly incomplete.

I definitely support removing any trace of it from the docs.

Add example commands that admins may use to search for rulesets and
users that might reference the to-be-deleted pool.

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'.
