> Porting per-CF set metrics for RPC times and response sizes from 0.89-fb to
> trunk. For each "mutation signature" (a set of column families involved in an
> RPC request) we increment several metrics, allowing to monitor access
> patterns. We deal with guarding against an explosion of the number of
> metrics in HBASE-4638 (which might even be implemented as part of this JIRA).
