> Per-user metrics will be useful in multi-tenant cases where we can emit number of requests, operations, num RPCs etc at the per-user aggregate level per regionserver. We currently have throttles per user, but no way to monitor resource usage per-user. 
> Looking at these metrics, operators can adjust throttles, do capacity planning, etc per-user.
