THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!

All of the following will be added via Kafka's metrics library like most of the metrics in the Kafka brokers and other components. The context of all metrics are limited to the worker where the metrics are being reported, and all metrics are defined as attributes on the specified MBean attribute and are measured within the context of a single worker. All metrics defined below are at the INFO recording level.
