Instead of using an Atomic Reference to data and aborting when we detect
that new data comes in, use the native cancellation/pre-emption features
of Java Future.
Behavior prior to these changes is to call expireServer(), log exception and suppress it. These changes will result in RS receiving the YouAreDeadException and treating it as a fatal error. This 'fail fast' approach will help us stabilize the code. This behavior can be reconsidered later if necessary.

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.
