MutableRate seemed a good candidate for the stats that we want to collect. Updated the patch to use that. For MutableRate, I have enabled showing extended stats like stdev, min/max etc. by default. In the future, we can add a config to toggle this if we see any particular overhead. Regarding using a Singleton, if I don't do this, the tests fail complaining of already existing metrics for FSDurations. Even QueueMetrics has a static map that it re-uses.
