glusterd: keep snapshot bricks separate from regular ones

The problem here is that a volume's transport options can change, but
any snapshots' bricks don't follow along even though they're now
incompatible (with respect to multiplexing).  This was causing the
USS+SSL test to fail.  By keeping the snapshot bricks separate
(though still potentially multiplexed with other snapshot bricks
including those for other volumes) we can ensure that they remain
unaffected by changes to their parent volumes.

Also fixed various issues with how the test waits (or more precisely
didn't) for various events to complete before it continues.
