Dogstatsd doesn't support sending deltas for gauges, so we must maintain the raw gauge value ourselves.

lv.Spaces don't support carrying over values from previous flush periods, so this implementation duplicateslv.Space's label value tree logic to map toGauges rather than observations. The simpler implementation of https://github.com/go-kit/kit/blob/master/metrics/graphite/graphite.go#L69 won't fly here because Dogstatsd supports tags, and we need to return the sameGaugeevery time for a given (name, lvs...) tuple. The changes also add tracking for whether a gauge was written in a flush period to avoid sending every gauge value every time.Also adds support for the tag analogue of the prefix parameter to
