Hello folks,

I'd like to propose the following KIP to improve the Kafka Streams metrics
mechanism to users. This includes 1) a minor change in the public
StreamsMetrics API, and 2) a major cleanup on the Streams' own built-in
metrics hierarchy.

Details can be found here:

I'd love to hear your thoughts and feedbacks. Thanks!
