Kafka Streams: add granular metrics per node and per task, also expose ability to register non latency metrics in StreamsMetrics
Also added different recording levels to Metrics.
This is joint contribution from Eno Thereska and Aarti Gupta.
from https://github.com/apache/kafka/pull/1362#issuecomment-218326690-------
We can consider adding metrics for process / punctuate / commit rate at the granularity of each processor node in addition to the global rate mentioned above. This is very helpful in debugging.
We can consider adding rate / total cumulated metrics for context.forward indicating how many records were forwarded downstream from this processor node as well. This is helpful in debugging.
We can consider adding metrics for each stream partition timestamp.
This is helpful in debugging.
## Besides the latency metrics, we can also add throughput latency in terms of source records consumed.

Jason recently cleaned things up significantly by consolidating the Message/Record classes
into the common Java code in the clients module. While reviewing that, I noticed a few things
that could be improved a little more. To make reviewing easier, there will be multiple PRs.

The original Javadoc description for `ConsumerRecord` is slightly confusing in that it can be read in a way such that an object is a key value pair received from Kafka, but (only) consists of the metadata associated with the record. This PR makes it clearer that the metadata is _included_ with the record, and moves the comma so that the phrase "topic name and partition number" in the sentence is more closely associated with the phrase "from which the record is being received".
