cluster/afr: Do self-heal in the background.
This patch introduces a new option "background-self-heal-count", with a
default value of 16.
This means that upto {background-self-heal-count} number of files/directories
will be healed in the background at any given time. If such number of self-heals
are already in progress, further self-heals take place in the foreground.

BUG: 320 (Improve self-heal performance)
