Though out the tutorial, the name of the input topic that was created is `streams-plaintext-input`. However, this was mistaken at some point in the tutorial and changed to `streams-wordcount-input`.
This patch is to adjust that. Thanks.

doneFuture is supposed to be completed with an empty string (meaning success) or a non-empty string which is the error message. Currently, due to exception.getMessage sometimes returning null or an empty string, this is not working correctly. This patch fixes that.

A broken can have more than one instance of ZooKeeperClient. For example, SimpleAclAuthorizer creates a separate ZooKeeperClient instance when configured.
This commit makes it possible to optionally specify the name for the ZooKeeperClient instance. The name is specified only for a broker's ZooKeeperClient instances, but not for commands' and tests'.

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().

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.

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.
