Closes#2490 from amethystic/kafka4727_server_config_doc_update
In https://issues.apache.org/jira/browse/KAFKA-4521 we fixed a potential message reorder bug in MM. However, the patch introduced another bug that can cause deadlock during MM shutdown. The deadlock will happen if zookeeper listener thread call requestAndWaitForCommit() after MirrorMaker thread has already exited loop of consuming and producing messages.
This patch fixes the problem by setting `iter` to `null` in `MirrorMakerOldConsumer.cleanup()`. If zookeeper listener thread calls `requestAndWaitForCommit()` after `cleanup()`, then it will not block waiting for commit notification since `iter == null`. If zookeeper listener thread calls `requestAndWaitForCommit()` before `cleanup()`, then `cleanup()` will call `notifyAll()` to unblock zookeeper listener thread.

Delay the cleanup of state directories that are not locked and not owned by the current thread such that we only remove the directory if its last modified is < now - cleanupDelayMs.
This also helps to avoid a race between threads on the same instance, where during rebalance, one thread releases the lock on the state directory, and before another thread can take the lock, the cleanup runs and removes the data.

This is a refactoring follow-up of https://github.com/apache/kafka/pull/2166. Main refactoring changes:
1. Extract `InMemoryKeyValueStore` out of `InMemoryKeyValueStoreSupplier` and remove its duplicates in test package.
2. Add two abstract classes `AbstractKeyValueIterator` and `AbstractKeyValueStore` to collapse common functional logics.
3. Added specialized `BytesXXStore` to accommodate cases where key value types are Bytes / byte[] so that we can save calling the dummy serdes.
4. Make the key type in `ThreadCache` from byte[] to Bytes, as SessionStore / WindowStore's result serialized bytes are in the form of Bytes anyways, so that we can save unnecessary `Bytes.get()` and `Bytes.wrap(bytes)`.
Each of these should arguably be a separate PR and I apologize for the mess, this is because this branch was extracted from a rather large diff that has multiple refactoring mingled together and dguy and myself have already put lots of efforts to break it down to a few separate PRs, and this is the only left-over work. Such PR won't happen in the future.

The issue of transiently having duplicates is due to the bad design of the left join itself: in order to ignore the partial joined results such as `A:null`, it lets the producer to potentially send twice to source stream one and rely on all the following conditions to be true in order to pass the test:
1. `receiveMessages` happen to have fetched all the produced results and have committed offsets.
2. streams app happen to have completed sending all result data.
3. consumer used in `receiveMessages` will complete getting all messages in a single poll().
If any of the above is not true, the test fails.
Fixed this test to add a filter right after left join to filter out partial joined results. Minor cleanup on integration test utils.

Kafka brokers have a config called "offsets.topic.replication.factor" that specify the replication factor for the "__consumer_offsets" topic. The problem is that this config isn't being enforced. If an attempt to create the internal topic is made when there are fewer brokers than "offsets.topic.replication.factor", the topic ends up getting created anyway with the current number of live brokers. The current behavior is pretty surprising when you have clients or tooling running as the cluster is getting setup. Even if your cluster ends up being huge, you'll find out much later that __consumer_offsets was setup with no replication.
The cluster not meeting the "offsets.topic.replication.factor" requirement on the internal topic is another way of saying the cluster isn't fully setup yet.
The right behavior should be for "offsets.topic.replication.factor" to be enforced. Topic creation of the internal topic should fail with GROUP_COORDINATOR_NOT_AVAILABLE until the "offsets.topic.replication.factor" requirement is met. This closely resembles the behavior of regular topic creation when the requested replication factor exceeds the current size of the cluster, as the request fails with error INVALID_REPLICATION_FACTOR.
