afr: Add throttled background client-side heals
Backport of: http://review.gluster.org/13207
If a heal is needed after inode refresh (lookup, read_txn), launch it in
the background instead of blocking the fop (that triggered refresh)
until the heal happens.
afr_replies_interpret() is modified such that the heal is
launched only if atleast one sink brick is up.
Max. no of heals that can happen in parallel is configurable via the
'background-self-heal-count' volume option. Any number greater than that
is put in a wait queue whose length is configurable via
'heal-wait-queue-leng' volume option. If the wait queue is also full,
further heals will be ignored.
Default values: background-self-heal-count=8, heal-wait-queue-leng=128
