There is a possibility that the state directory locking fails when another stream thread is taking long to close all tasks. Simple retries should alleviate the problem.

My bad. I removed ZOOKEEPER_CONNECT_CONFIG from consumer's config by mistake. It is needed by our own partition assigner running in consumers.

See KIP-31 and KIP-32 for details.
A few notes on the patch:
1. This patch implements KIP-31 and KIP-32. The patch includes features in both KAFKA-3025, KAFKA-3026 and KAFKA-3036
2. All unit tests passed.
3. The unit tests were run with new and old message format.
4. When message format conversion occurs during consumption, the consumer will not be able to detect the message size too large situation. I did not try to fix this because the situation seems rare and only happen during migration phase.

* We need to poll periodically even when all partitions are paused in order to respond to a possible rebalance promptly.
* There is a race condition when two (or more) threads try to clean up the same state directory. One of the thread fails with FileNotFoundException. Thus the new code simply catches it and ignore.

* During window store initialization, we have to open segments in the segment id order and update ```currentSegmentId```, otherwise cleanup won't work.
* ```getSegment()``` should not create a segment and clean up old segments if the segment id is greater than ```currentSegmentId```. Segment maintenance should be driven not by query but only by data insertion.

A window store should open all existing segments. This is important for segment cleanup, and it also ensures that the first fetch() call returns the hits, the values in the search range. (previously, it missed the hits in fetch() immediately after initialization).

* RocksDBStore.putInternal should bypass logging.
* StoreChangeLogger should not call context.recordCollector() when nothing to log
* This is for standby tasks. In standby task, recordCollector() throws an exception. There should be nothing to log anyway.
* fixed ConcurrentModificationException in StreamThread
