I think we should find a way to treat counters, timers, sets, and a gauges in a generic way. The 'STATSD_' prefix on these indicates that we don't treat them generically, but treat them in a way that is implementation-detail-of-statsd-specific.

After ingestion occurs, we should treat a timer coming from statsd identical to a timer coming from codahale metrics identical to one from some unknown pre-aggregator.
