Ben Johnson c6ca86f2d9 Add ExpvarStatsClient and basic tracking. ... A `StatsClient` for `expvar` is added so we can track Stats through the `/debug/vars` endpoint. Tags are nested inside maps so that we can see stats for db, frame & slice. Also added a `MultiStatsClient` for chaining multiple `StatsClient` implementations together (e.g. `expvar` and DataDog).		2016-10-20 14:35:14 -06:00
