Closes#1940 from mjsax/hotfix-resetTool
Changed the ordering in `StreamThread.shutdown`
1. commitAll (we need to commit so that any cached data is flushed through the topology)
2. close all tasks
3. producer.flush() - so any records produced during close are flushed and we have offsets for them
4. close all state managers
5. close producers/consumers
6. remove the tasks
Also in `onPartitionsRevoked`
1. commitAll
2. close all tasks
3. producer.flush
4. close all state managers

This PR implements KIP-78:Cluster Identifiers [(link)](https://cwiki.apache.org/confluence/display/KAFKA/KIP-78%3A+Cluster+Id#KIP-78:ClusterId-Overview) and includes the following changes:
1. Changes to broker code
- generate cluster id and store it in Zookeeper
- update protocol to add cluster id to metadata request and response
- add ClusterResourceListener interface, ClusterResource class and ClusterMetadataListeners utility class
- send ClusterResource events to the metric reporters
2. Changes to client code
- update Cluster and Metadata code to support cluster id
- update clients for sending ClusterResource events to interceptors, (de)serializers and metric reporters
3. Integration tests for interceptors, (de)serializers and metric reporters for clients and for protocol changes and metric reporters for broker.
4. System tests for upgrading from previous versions.

This is joint work between dguy and enothereska. The work implements KIP-63. Overview of main changes:
- New byte-based cache that acts as a buffer for any persistent store and for forwarding changes downstream.
- Forwarding record path changes: previously a record in a task completed end-to-end. Now it may be buffered in a processor node while other records complete in the task.
- Cleanup and state stores and decoupling of cache from state store and forwarding.
- More than 80 new unit and integration tests.

Set the NUM_STREAM_THREADS_CONFIG = 1 in SmokeTestClient as we get locking issues when we have NUM_STREAM_THREADS_CONFIG > 1 and we have Standby Tasks, i.e., replicas. This is because the Standby Tasks can be assigned to the same KafkaStreams instance as the active task, hence the directory is locked

Closes#1804 from dguy/kafka-4104
There's a minor bug in ProcessorTopologyTestDriver that prevents it from working with a topology that contains multiple sources. The bug is that ```consumer.assign()``` is called while looping through all the source topics, but, consumer.assign resets the state of the MockConsumer to only consume from the topics passed in. This patch fixes the issue by calling consumer.assign once with all the TopicPartition instances. Unit test (testDrivingSimpleMultiSourceTopology) included.

guozhangwang enothereska mjsax miguno please take a look. A few things that need to be clarified
1. I've added StreamsConfig.USER_ENDPOINT_CONFIG, but should we have separate configs for host and port or is this one config ok?
2. `HostState` in the KIP has a byte[] field - not sure why and what it would be populated with
3. I've changed the API to return `List<KafkaStreamsInstance>` as opposed to `Map<HostInfo, Set<TaskMetadata>>` as i find this far more intuitive to work with.

This cleans up misbehaviour that was introduce while fixing KAFKA-3817. It is impossible for a non-count aggregate to be build, when the addition happens before the removal. IMHO making sure that these details are correct is very important.
This PR has local test errors. It somehow fails the ResetIntegrationTest. It doesn't quite appear to me why but it looks like this PR breaks it, especially because the error appears with the ordering of the events. Still I am unable to find where I could have broken it. Maybe not seems to fail on trunk aswell.

The KafkaStreamsTest can occasionally hang if the test doesn't run fast enough. This is due to there being no brokers available on the broker.urls provided to the StreamsConfig. The KafkaConsumer does a poll and blocks causing the test to never complete.
