> During assignment, each table balancer starts assigning tablets in order.  This ensures
the the "lowest" tabletserver gets at least one tablet for each table.  This can make for
an unbalanced cluster when there are many small tables.  Randomize the list of tablets in
the DefaultLoadBalancer to evenly distribute tablets on a new cluster.
