      Description

      The metrics measuring RPC latencies capture average / min / max, which isn't so interesting for latency distributions. We have HistogramMetric and should use it.

      Doing so requires implementing HistogramMetric::Reset() so that we keep the functionality that already exists in /rpcz.
