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|https://github.com/apache/kafka/blob/a2ee0855ee5e73f3a74555d52294bb4acfd28945/server/src/main/java/org/apache/kafka/server/ClientMetricsManager.java#L115], and BrokerServer#shudown doesn't close ClientMetricsManager which let the timer thread still runs in background. -- This message was sent by Atlassian Jira (v8.20.10#820010)
