This commit copies the pylintrc file that apache yetus uses for itself
to HBase.
Differences:
- Yetus uses 2 space indents and the initial consensus
in the JIRA discussion asked for 4 space indents (as
called for in PEP 8)

-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)

Modified jruby scripts to pick up drainingZNode and masterAddressZNode
correctly, from within znodePaths in ZooKeeperWatcher. Modified
get-active-master.rb to retrieve server name using MasterAddressTracker
instead of ZKUtil.
Tested on a standalone HBase deployment to check that the scripts work
as expected.

Unit test (TestAssignmentManager) uses mock which always aggregates. So added trace level log message and verified manually on a single node cluster.

Hadoop 3.x added some new dependencies that refer to the apache license
by it's older title (from apache parent pom 14 and earlier). Instead of
listing them all individually, we can group them under ASL for our
LICENSE file.
