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.

Closes#2074 from vahidhashemian/KAFKA-3853
This PR is extracted from https://github.com/apache/kafka/pull/2333 as an incremental fix to ease the reviewing:
1. Removed `storeToProcessorNodeMap` from ProcessorTopology since it was previously used to set the context current record, and can now be replaced with the dirty entry in the named cache.
2. Replaced `sourceStoreToSourceTopic` from ProcessorTopology with `storeToChangelogTopic` map, which includes the corresponding changelog topic name for all stores that are changelog enabled.
3. Modified `ProcessorStateManager` to rely on `sourceStoreToSourceTopic` when retrieving the changelog topic; this makes the second parameter `loggingEnabled` in `register` not needed any more, and we can deprecate the old API with a new one.
4. Also fixed a minor issue in `KStreamBuilder`: if the storeName is not provided in the `table(..)` function, do not create the underlying materialized store. Modified the unit tests to cover this case.
5. Fixed a bunch of other unit tests failures that are exposed by this refactoring, in which we are not setting the applicationId correctly when constructing the mocking processor topology.

Add Global Tables to KafkaStreams. Global Tables are fully replicated once-per instance of KafkaStreams. A single thread is used to update them. They can be used to join with KStreams, KTables, and other GlobalKTables. When participating in a join a GlobalKTable is only ever used to perform a lookup, i.e., it will never cause data to be forwarded to downstream processor nodes.

Here's my first pass at finer grained auto offset reset strategies.
I've left TODO comments about whether we want to consider adding this to `KGroupedTable.aggregate` and `KStreamImpl` when re-partitioning a source.

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.
