Review request for Ambari, Aravindan Vijayan, Dmytro Sen, and Sumit Mohanty.


Bugs: AMBARI-17799
    https://issues.apache.org/jira/browse/AMBARI-17799


Repository: ambari


Description
-------

AMS stack script delete ZK data because when standalone HBase restarts, the ZK 
data quite frequently gets corrupt and the restart is no longer works. 

This is because all daemon run inside the same JVM. We had to do this as a 
workaround after which restart of AMS in embedded mode became reliable

With HBASE-16244, the standalone mode restart will succeed and we do not need 
to cleanup zookeeper data
