Closes#883 from ymatsuda/minor
* 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

We need to close producer first before closing tasks to make sure all messages are acked and hence checkpoint offsets are updated before closing tasks and their state. It was re-ordered mistakenly before.

Closes#845 from guozhangwang/KStreamState
Changes include:
1) Move logging logic from MeteredXXXStore to internal stores, and leave WindowedStore API clean by removed all internalPut/Get functions.
2) Wrap common logging behavior of InMemory and LRUCache stores into one class.
3) Fix a bug for StoreChangeLogger where byte arrays are not comparable in HashSet by using a specified RawStoreChangeLogger.
4) Add a caching layer on top of RocksDBStore with object caching, it relies on the object's equals and hashCode function to be consistent with serdes.

Closes#816 from ymatsuda/remove_obsolete_class
It behaves better on Windows and provides more useful error messages.
Also:
* Minor inconsistency fix in `kafka.server.OffsetCheckpoint`.
* Remove delete from `streams.state.OffsetCheckpoint` constructor (similar to the change in `kafka.server.OffsetCheckpoint` in 836cb19633 (diff-2503b32f29cbbd61ed8316f127829455L29)).

An implementation of local store for join window. This implementation uses "rolling" of RocksDB instances for timestamp based truncation.

At DAG level, `KTable<K,V>` sends (key, (new value, old value)) to down stream. This is done by wrapping the new value and the old value in an instance of `Change<V>` class and sending it as a "value" part of the stream. The old value is omitted (set to null) by default for optimization. When any downstream processor needs to use the old value, the framework should enable it (see `KTableImpl.enableSendingOldValues()` and implementations of `KTableProcessorSupplier.enableSensingOldValues()`).
NOTE: This is meant to be used by aggregation. But, if there is a use case like a SQL database trigger, we can add a new KTable method to expose this.
