    STORM-2954 add HBase metricstore implementation

    This provides an HBase metricstore implementation to optionally replace the 
default RocksDB version.  It allows both Nimbus and Supervisors to insert 
metrics directly into HBase.
    The code should allow for multiple hosts/threads per host to insert into 
HBase.  Where new metadata or aggregated metrics are added, HBase checkandput 
calls are made with retries to make sure the latest data is fetched and stored.
    The docs provide info on the configuration options, schema, and how to 
create a table for usage.
    I ran my unit tests against HBase 1.1.12, and tested on a secure 1.3 (with 
modified internal code) HBase setup.
