Description

We want built-in metrics in CommonStats and [Spout|Bolt]ExecutorStats to use codahale Meter directly.

Each worker process should keep a MetricRegistry and have a configurable set of reporters that can be instantiated.

Other reporters can be added for the registry for direct reporting to the metric backend of choice.

Note that I am proposing we leave old metrics through ZooKeeper in place after this task (taken care of by STORM-2168), but we can change this if others prefer to go cold turkey.
