Add utility to entirely clear out ZK
------------------------------------
Key: HBASE-4268
URL: https://issues.apache.org/jira/browse/HBASE-4268
Project: HBase
Issue Type: New Feature
Components: scripts
Affects Versions: 0.92.0
Reporter: Todd Lipcon
In disaster scenarios, sometimes some cruft is left over in ZK, when it would
be better to do a truely clean startup. We should add a script which allows the
admin to clear out ZK while the cluster is down.
