> This will add three metric types:
> AvgMinMaxCounterSet
> AvgMinMaxPercentileCounter
> AvgMinMaxPercentileCounterSet
> The percentile metrics allow us to get a better sense of the latency distribution. They
are more expensive than AvgMinMax counters and are restricted to latency measurements for
now.
> The counter set allows the grouping of metrics such as write per namespace, read per
namespace.
