HBASE-19787 Fix or disable tests broken in branch-2 so can cut beta-1

M dev-support/make_rc.sh
  Disable checkstyle building site. Its an issue being fixed over in HBASE-19780

M hbase-server/src/main/java/org/apache/hadoop/hbase/master/HMaster.java
  The clusterid was being set into the process only after the
  regionserver registers with the Master. That can be too late for some
  test clients in particular. e.g. TestZKAsyncRegistry needs it as soon
  as it goes to run which could be before Master had called its run
  method  which is regionserver run method which then calls back to the
  master to register itself... and only then do we set the clusterid.
  HBASE-19694 changed start order which made it so this test failed.
  Setting the clusterid right after we set it in zk makes the test pass.

  Another change was that backup masters were not going down on stop.
  Backup masters were sleeping for the default zk period which is 90
  seconds. They were not being woken up to check for stop. On stop
  master now tells active master manager.

M hbase-server/src/test/java/org/apache/hadoop/hbase/TestJMXConnectorServer.java
  Prevent creation of acl table. Messes up our being able to go down
  promptly.

M hbase-server/src/test/java/org/apache/hadoop/hbase/master/balancer/TestRegionsOnMasterOptions.java
M hbase-server/src/test/java/org/apache/hadoop/hbase/client/TestMultiParallel.java
M hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/TestRegionServerReadRequestMetrics.java
  Disabled for now because it wants to run with regions on the Master...
  currently broke!

M hbase-server/src/test/java/org/apache/hadoop/hbase/client/TestZKAsyncRegistry.java
  Add a bit of debugging.

M hbase-server/src/test/java/org/apache/hadoop/hbase/master/TestDLSAsyncFSWAL.java
  Disabled. Fails 40% of the time.

M hbase-server/src/test/java/org/apache/hadoop/hbase/master/TestDLSFSHLog.java
  Disabled. Fails 33% of the time.

Disabled stochastic load balancer for favored nodes because it fails on
occasion and we are not doing favored nodes in branch-2.
