Title: Optionally filter data reported to Librato Metrics

This differs from #19 in that I have a plethora of gauges but only report on a select few. I can't use `:only => [ :count ]` because I don't necessarily want _all_ counts. I would rather use `:only => [ 'my_app.count', 'my_app.95th_percentile' ]`.
