features/bitrot: refactor brick connection logic

    Backport of http://review.gluster.org/10763

Brick connection was bloated (and not implemented efficiently) with
calls which were not required to be called under lock. This resulted
in starvation of lock by critical code paths. This eventally did not
scale when the number of bricks per volume increases (add-brick and
the likes).

Also, this patch cleans up some of the weird reconnection logic that
added more to the starvation of resources and cleans up uncontrolled
growing of log files.
