Changes the configuration hbase.balancer.tablesOnMaster from list of
table names to instead be a boolean; true if master carries
tables/regions and false if it does not.
Adds a new configuration hbase.balancer.tablesOnMaster.systemTablesOnly.
If true, hbase.balancer.tablesOnMaster is considered true but only
system tables are put on the master.

Master was claiming itself active master though it had stopped. Fix
the activeMaster flag. Set it to false on exit.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/LoadBalancer.java
Add new configs and convenience methods for getting current state of
settings.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/balancer/BaseLoadBalancer.java
Move configs up into super Interface and now the settings mean
different, remove the no longer needed processing.
* calls to methods getLowestLocalityRegionServer() & getLeastLoadedTopServerForRegion() got removed in HBASE-18164
* call to calculateRegionServerLocalities() got removed in HBASE-15486
* Some other minor improvements

Before this commit, BucketCache always used the default values.
This commit adds the ability to configure these values.

Add in hbase-thirdparty hbase-shaded-netty instead.
s/io.netty/org.apache.hadoop.hbase.shaded.io.netty/ everywhere in hbase.
Also set a system property when running tests and when starting
hbase; required by netty so can find the relocation files in the
bundled .so.
If an unassign is unable to communicate with its target server,
expire the server and then wait on a signal from ServerCrashProcedure
before proceeding. The unassign has lock on the region so no one else
can proceed till we complete. We prevent any subsequent assign from
running until logs have been split for crashed server.
In AssignProcedure, do not assign if table is DISABLING or DISABLED.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/RegionTransitionProcedure.java
Change remoteCallFailed so it returns boolean on whether implementor
wants to stay suspended or not.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/UnassignProcedure.java
Doc. Also, if we are unable to talk to remote server, expire it and
then wait on SCP to wake us up after it has processed logs for failed
server.

This test as it is written currently will not work with AMv2. This needs to be re-written after HBASE-18511 is committed. Disabled the test and update JIRA to re-enable it with dependency on HBASE-18511.

* Modified AssignmentManager.processAssignQueue() method to consider only highest versioned region servers for system table regions when
destination server is not specified for them. Destination server is retained, if specified.
* Modified MoveRegionProcedure to allow null value for destination server i.e. moving a region from specific source server to non-specific/ unknown
destination server (picked by load-balancer) is supported now.
* Removed destination server selection from HMaster.checkIfShouldMoveSystemRegionAsync(), as destination server will be picked by load balancer
