The use of consumer.poll() made the test flaky since in some cases, it doesn't wait for coordinator connection.

The Java API can pass a Properties object to StreamsBuilder#build, to allow, e.g., topology optimization, while the Scala API does not yet. The latter only delegates the work to the underlying Java implementation.

This is a draft cleanup for KAFKA-7502. Here is the details:
* Make KTableKTableJoinNode abstract, and define its child classes ([NonMaterialized,Materialized]KTableKTableJoinNode) instead: now, all materialization-related routines are separated into the other classes.
* KTableKTableJoinNodeBuilder#build now instantiates [NonMaterialized,Materialized]KTableKTableJoinNode classes instead of KTableKTableJoinNode.

Adds a new listener config `max.connections` to limit the number of active connections on each listener. The config may be prefixed with listener prefix. This limit may be dynamically reconfigured without restarting the broker.
This is one of the PRs for KIP-402 (https://cwiki.apache.org/confluence/display/KAFKA/KIP-402%3A+Improve+fairness+in+SocketServer+processors). Note that this is currently built on top of PR #6022

Users have reported (KAFKA-7565) that when consumer poll wake up is used,
it is possible to receive fetch responses that don't match the copied topic
partitions collection for the session when the fetch request was created.
This commit improves the error handling here by throwing an
IllegalStateException instead of a NullPointerException. And by
generating a message for the exception that includes a bit of more
information.

It is best to use a growing thread pool for worker cleanups. This lets us ensure that we close workers as fast as possible and not get slowed down on blocking cleanups.

When unclean leader election is enabled dynamically on brokers, we notify controller of the update before updating KafkaConfig. When processing this event, controller's decision to elect unclean leaders is based on the current KafkaConfig, so there is a small timing window when the controller may not elect unclean leader because KafkaConfig of the server was not yet updated. The commit fixes this timing window by using the existing BrokerReconfigurable interface used by other classes which rely on the current value of KafkaConfig.

DynamicBrokerReconfigurationTest.testAddRemoveSaslListeners removes a listener, waits for the config to be propagated to all brokers and then validates that connections to the removed listener fail. But there is a small timing window between config update and Processor shutdown. Before validating that connections to a removed listener fail, this commit waits for all metrics of the removed listener to be deleted, ensuring that the Processors of the listener have been shutdown.

After the 2.1 release, if the broker hasn't been upgrade to the latest inter-broker protocol version, the committed offsets stored in the __consumer_offset topic will get cleaned up way earlier than it should be when the offsets are loaded back from the __consumer_offset topic in GroupCoordinator, which will happen during leadership transition or after broker bounce. This patch fixes the bug by setting expireTimestamp to None if it is the default value after loading v1 offset records from __consumer_offsets.

For consumers using SSL, this timeout includes the time to create and copy keystores and truststores and sometime it takes longer than 10s to complete the security setup before starting the consumer process.

Test currently checks that there were at least 5 polls when 5 connections are established with connectionQueueSize=1. But we could be doing the check just after the 5th connection before the 5th poll, so updated the check to verify that there were at least 4 polls.

Metadata may be updated from the background thread, so we need to protect access to SubscriptionState. This patch restructures the metadata handling so that we only check pattern subscriptions in the foreground. Additionally, it improves the following:
1. SubscriptionState is now the source of truth for the topics that will be fetched. We had a lot of messy logic previously to try and keep the the topic set in Metadata consistent with the subscription, so this simplifies the logic.
2. The metadata needs for the producer and consumer are quite different, so it made sense to separate the custom logic into separate extensions of Metadata. For example, only the producer requires topic expiration.
3. We've always had an edge case in which a metadata change with an inflight request may cause us to effectively miss an expected update. This patch implements a separate version inside Metadata which is bumped when the needed topics changes.
4. This patch removes the MetadataListener, which was the cause of https://issues.apache.org/jira/browse/KAFKA-7764.

In KAFKA-5503, we have added a check for `running` flag in the loop inside maybeWaitForProducerId. This is to handle concurrent call to Sender close(), while we attempt to get the ProducerId. This avoids blocking indefinitely when the producer is shutting down.
This created a corner case, where Sender thread gets blocked, if we had concurrent producerId reset and call to Sender thread close. The fix here is to check the `forceClose` flag in the loop inside maybeWaitForProducerId instead of the `running` flag.

SelectorTest.testCloseConnectionInClosingState sends and receives messages to get the channel into a state with staged receives and then waits for idle timeout to close the channel. When run with SSL, the channel may have buffered bytes that prevent the channel from being closed. Updated the test to wait until there are no buffered bytes as well.

Test uses 100ms as connections.max.reauth.ms and checks that a second reauthentication doesn't occur within the hard-coded 1 second minimum interval. But since the interval is small, we cannot guarantee that the time between the two checks is not higher than 1 second. Change the test to use MockTime so that we can control the time.

* Fix for KAFKA-7974: Avoid calling disconnect() when not connecting
* Resolve host only when currentAddress() is called
Moves away from automatically resolving the host when the connection entry is constructed, which can leave ClusterConnectionStates in a confused state.
Instead, resolution is done on demand, ensuring that the entry in the connection list is present even if the resolution failed.
* Add Javadoc to ClusterConnectionStates.connecting()
Improve JavaDocs about global state stores.
