Users often use the RocksDBConfigSetter to modify parameters such as cache or block size, which must be set through the BlockBasedTableConfig object. Rather than creating a new object in the config setter, however, users should most likely retrieve a reference to the existing one so as to not lose the other defaults (eg the BloomFilter)
There have been notes from the community that it is not obvious this should be done, nor is it immediately clear how to do so. This PR updates the RocksDBConfigSetter docs to hopefully improve things.
I also piggybacked a few minor cleanups in the docs

This PR intendent to address some typos in https://kafka.apache.org/documentation/streams/developer-guide/processor-api.html page.
Invalid configuration option specified in the example. I've replaced with closest constant TopicConfig.MIN_IN_SYNC_REPLICAS_CONFIG, since LogConfig.MinInSyncReplicasProp() requires Scala stuff
Reference to LogConfig seems to be obsolete, I believe I've moved it to correct line

Now that we can configure RocksDB to bound the total memory we should include docs describing how, as well as touching on some possible options that should be considered when taking advantage of this feature.

The old docs here used a now deprecated method to set the block cache size. In switching over to the new one we would now need to construct a Cache object and therefore also need to close it, so this is a good opportunity to demonstrate the RocksDBConfigSetter#close method that will need to be implemented by users.

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.

Implemented an in-memory window store allowing for range queries. A finite retention period defines how long records will be kept, ie the window of time for fetching, and the grace period defines the window within which late-arriving data may still be written to the store.
Unit tests were written to test the functionality of the window store, including its insert/update/delete and fetch operations. Single-record, all records, and range fetch were tested, for both time ranges and key ranges. The logging and metrics for late-arriving (dropped)records were tested as well as the ability to restore from a changelog.

Scala 2.12 has better support for newer Java versions and includes additional
compiler warnings that are helpful during development. In addition, Scala 2.11
hasn't been supported by the Scala community for a long time, the soon to be
released Spark 2.4.0 will finally support Scala 2.12 (this was the main reason
preventing many from upgrading to Scala 2.12) and Scala 2.13 is at the RC stage.
It's time to start recommending the Scala 2.12 build as we prepare support for
Scala 2.13 and start thinking about removing support for Scala 2.11.
In the meantime, Jenkins will continue to build all supported Scala versions (including
Scala 2.11) so the PR and trunk jobs will fail if people accidentally use methods
introduced in Scala 2.12.
