Kahlil Oppenheimer 3a79590bb4 HBASE-18164 Fast locality computation in balancer
-Added new LocalityCostFunction and LocalityCandidateGenerator that
cache localities of every region/rack combination and mappings of every
region to its most local server and to its most local rack.

-Made LocalityCostFunction incremental so that it only computes locality
based on most recent region moves/swaps, rather than recomputing the
locality of every region in the cluster at every iteration of the
balancer

-Changed locality cost function to reflect the ratio of:
(Current locality) / (Best locality possible given current cluster)
