    Description

      After profiling the kafka tests, tons of `client-metrics-reaper` thread not cleanup after BrokerServer shutdown.

      The thread client-metrics-reaper comes from ClientMetricsManager#expirationTimer, and BrokerServer#shudown doesn't close ClientMetricsManager which let the timer thread still runs in background.
