Part of KIP-572: follow up work to PR #9800. It's not save to retry a TX commit after a timeout, because it's unclear if the commit was successful or not, and thus on retry we might get an IllegalStateException. Instead, we will throw a TaskCorruptedException to retry the TX if the commit failed.

During the AK website upgrade, changes made to kafka-site weren't migrated back to kafka-docs.
This PR is an attempt at porting the streams changes to kafka/docs
For the most part, the bulk of the changes in the PR are cosmetic.

Add necessary documentation for KIP-450, adding sliding window aggregations to KStreams

- part of KIP-572
- removed the usage of `retries` in `GlobalStateManger`
- instead of retries the new `task.timeout.ms` config is used

- part of KIP-572
- deprecates producer config `retries` (still in use)
- deprecates admin config `retries` (still in use)
- deprecates Kafka Streams config `retries` (will be ignored)
- adds new Kafka Streams config `task.timeout.ms` (follow up PRs will leverage this new config)
Reviewers: John Roesler <john@confluent.io>, Jason Gustafson <jason@confluent.io>, Randall Hauch <randall@confluent.io>
Add docs for KIP-441 and KIP-613.
Fixed some miscellaneous unrelated issues in the docs:
* Adds some missing configs to the Streams config docs: max.task.idle.ms,topology.optimization, default.windowed.key.serde.inner.class, and default.windowed.value.serde.inner.class
* Defines the previously-undefined default windowed serde class configs, including choosing a default (null) and giving them a doc string, so the yshould nwo show up in the auto-generated general Kafka config docs
* Adds a note to warn users about the rocksDB bug that prevents setting a strict capacity limit and counting write buffer memory against the block cache

Closes#6490 from mjsax/minor-streams-docs-rocksdb
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.

Documentation changes for adding overloaded StreamsBuilder(java.util.Properties props) method in KIP-312
Reviewers: Matthias J. Sax <matthias@confluent.io>, Guozhang Wang <guozhang@confluent.io>
1. Rename metrics scope of rocksDB window and session stores; also modify the store metrics accordingly with guidance on its correlations to metricsScope.
2. Add the missing total metrics for per-thread, per-task, per-node and per-store sensors.

Updated the upgrade doc as well since we do not have an overloaded function without the deprecated parameter before. Also renamed the 1.2 release version to 2.0.

This PR implements a Scala wrapper library for Kafka Streams. The library is implemented as a project under streams, namely `:streams:streams-scala`. The PR contains the following:
* the library implementation of the wrapper abstractions
* the test suite
* the changes in `build.gradle` to build the library jar
The library has been tested running the tests as follows:
```
$ ./gradlew -Dtest.single=StreamToTableJoinScalaIntegrationTestImplicitSerdes streams:streams-scala:test
$ ./gradlew -Dtest.single=StreamToTableJoinScalaIntegrationTestImplicitSerdesWithAvro streams:streams-scala:test

This pull request targets https://issues.apache.org/jira/browse/KAFKA-6386
The minor fix to deprecate usage of `StreamsConfig` in favor of `java.util.Properties`.
I created separate public constructors using `Properties` in order to replace the old ones,
and prioritize new functions in the `KafkaStreams.java` file.
Since this is my first time doing open source contribution, I'm very happy to get
any comment or pointer to be more professional and get better next time, thank you Guozhang guozhangwang and Liquan Ishiihara!
testing strategy: existing unit test should be suffice to cover this change.

This is the polished version.
1. The old merge() method in StreamsBuilder has been removed,
2. The merge() method in KStreamBuilder was changed so that it would use the single variable argument
rather than several variable arguments in the KStreamImpl implementation
3. The merge() method in KStream has been declared as final and tests have been added to test correctness.
