3c43185002 doc: more details for pool deletion 
Prior to this change, the documention instructed administrators to
delete rulesets and users, but did not go into details regarding how to
do that.

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

117e63041a Correct typo 'restared' to 'restarted' 
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'.
