----------------------------------

Here's a patch which uses the HBase native metrics API.  There's a check for HBase version >= 1.4 for backwards compatibility, and a config flag.

> Add server level metrics for secondary indexes
> - Histogram metrics for time to complete all secondary index updates per primary table update per index type. Will help us trend perf over time and catch impending issues. 
> - Histogram metrics for number of updates dispatched to secondary index stores to service one primary table update per index type. Will help us catch inefficient behavior or problematic schema design. 
> - Count of deployed secondary indexes by type. Will help understand and trend index usage, or catch deploy of an unwanted index type.
