[jira] [Commented] (KAFKA-9730) add tag "partition" to BrokerTopicMetrics so as to observe the partition metrics on the same broker

   ```Partitioner``` enable us to dispatch the data to the specify partition as we wish. However, we can't observe the partition metrics if they are on the same broker. The root cause is that the key of topic metrics doesn't contain "partition" so all partitions on the same broker are merged into single metrics (see attachment).
