Description

Creating an umbrella ticket to track improvement of BrokerTopicMetrics reporting.
Some of the tasks are:

• Add a metric for total fetch/produce requests as opposed to simply failure counts
• Tracking offset commit requests separately from produce requests
• Adding a metric to track bad requests from clients. (HTTP 4XX vs 5XX as an example).
