Review request for hbase and Ryan Rawson.
Summary
-------
Fix for pathological balancer. Mostly logging changes to remove confusion as
to what the balancer is up to but also removed a mistake where we'd always give
a server one region ('just in case") if regions to assign though it might be a
server that is loaded. In clusters w/ lots of nodes with a few of the nodes
not in-balance, the lightly loaded nodes would never get regions so we'd just
keep reassigning and never settle.
This addresses bug hbase-2617.
