Description

The request rate metrics in BrokerTopicMetrics are incremented per partition in a Produce request. If a produce requests has multiple partitions for the same topic in the request, then the request will get counted multiple times.

This is inconsistent with how we count request rate metrics elsewhere.

The same applies to the TotalFetchRequest rate metric
