Review comment:
`MetricLogger` stores separate metric values from `MetricEnvironment`
for reporting a single aggregated result to the logger. In this PR, it's used
for keeping process-wide API latency histogram values and periodically logging
it. So I think changing `MetricEnvironment` doesn't have any effect here.
