hudeqi updated KAFKA-14868:
---------------------------
Description: In some current classes, some metrics are always registered
when loading, but it often occurs that some or all metrics are forgotten to be
removed when closing. Therefore, increase the counting capability in
KafkaMetricsGroup. When using the method of KafkaMetricsGroup to add or remove
a metric, it will add 1 to the corresponding counter, so that you can check
whether there is a forgotten metric to be removed by counting and comparing in
the unit test of the corresponding class.
> Add metric counting capability to KafkaMetricsGroup to facilitate checking
> that the metric is missed when it is closed
