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

Mark the store as open after the DB has been restored from the changelog.
Only add the store to the map in ProcessorStateManager post restore.
Make RocksDBWindowStore.Segment override openDB(..) as it needs to mark the Segment as open.
Throw InvalidStateStoreException if any stores in a KafkaStreams instance are not available.

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.

Closes#1649 from dguy/kafka-3929
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.
