Closes#2416 from hachikuji/refactor-partition-lag-cleanup
There is a slight change of behaviour: we now complete the `Future` returned from `send`
before the callbacks are invoked. This seems OK and perhaps a little better as the `Future`
can make progress sooner (as it would typically be blocked on a different thread than the
I/O thread that invokes the callbacks).

Closes#2350 from enothereska/minor-broker-level-config
Issue: https://issues.apache.org/jira/browse/KAFKA-4614
Fixes the problem that the broker threads suffered by long GC pause.
When GC thread collects mmap objects which were created for index files, it unmaps memory mapping so kernel turns to delete a file physically. This work may transparently read file's metadata from physical disk if it's not available on cache.
This seems to happen typically when we're using G1GC, due to it's strategy to left a garbage for a long time if other objects in the same region are still alive.
See the link for the details.

Fixes KAFKA-3857
Changes proposed in this pull request:
An additional log cleaner metric has been added:
time-since-last-run-ms: Time since the last log cleaner run, in milliseconds. This metric would be reset to 0 every time log cleaner thread runs. If this metric keeps constantly increasing, it indicates that the log cleaner thread is not alive.
If you are creating alerts around log cleaner, you could monitor this metric. A high "time-since-last-run-ms" value (eg: 600000) indicates that the log cleaner hasn't been running since the last 10 minutes.
The code has been tested. JMX metric has been verified.
Note: This pull request is a continuation of the following pull request. PR#1593 was quite old and I had some trouble rebasing it. Decided to start a fresh PR.

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.
