The goal of this task is to implement an integration test for the kafka stream metrics.
We have to check 2 things:
1. After streams application are started, all metrics from different levels (thread, task, processor, store, cache) are correctly created and displaying recorded values.
2. When streams application are shutdown, all metrics are correctly de-registered and removed.

- The flaky failure is caused by the fact that the main thread sometimes issues DescribeConsumerGroup request before the consumer assignment takes effect. Added a latch to make sure such situation is not going to happen.

In a previous commit #6091, we've fixed a couple of edge cases and hence do not need to remove state listener anymore (before that we removed the state listener intentionally to avoid some race conditions, which has been gone for now).

This patch adds additional DEBUG statements in AbstractIndex.scala, OffsetIndex.scala, and TimeIndex.scala. It also changes the logging on append from DEBUG to TRACE to make DEBUG logging less disruptive, and it ensures that exceptions raised from index classes include file/offset information.

Shutdown session expiry thread prior to closing ZooKeeper client to ensure that new clients are not created by the expiry thread and left active when returning from ZooKeeperClient.close().
Reviewers: Ismael Juma <ismael@juma.me.uk>
TopicDescription and ConsumerGroupDescription in org.apache.kafka.clients.admin. are part of the public API, so we should retain the existing public constructor. Changed the new constructor with authorized operations to be package-private to avoid maintaining more public constructors since we only expect admin client to use this.
Reviewers: Manikumar Reddy <manikumar.reddy@gmail.com>
We verify that ZK clients are closed in tests since these can affect subsequent tests and that makes it hard to debug test failures. But because of changes to ZooKeeper client, we were checking the wrong thread name. The thread name used now is <creatorThreadName>-EventThread where creatorThreadName varies depending on the test. Fixed ZooKeeperTestHarness to check this format and fixed tests which were leaving ZK clients behind. Also added a test to make sure we can detect changes to the thread name when we update ZK clients in future.

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.

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.
