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.

Serdes are confusing in the Scala wrapper:
* We have wrappers around Serializer, Deserializer and Serde which are not very useful.
* We have Serdes in 2 places org.apache.kafka.common.serialization.Serde and in DefaultSerdes, instead we should be having only one place where to find all the Serdes.
I wanted to do this PR before the release as this is a breaking change.
This shouldn't add more so the current tests should be enough.

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.

Several build and documentation updates were required after the merge of KAFKA-6670: Implement a Scala wrapper library for Kafka Streams.
Encode Scala major version into streams-scala artifacts.
To differentiate versions of the kafka-streams-scala artifact across Scala major versions it's required to encode the version into the artifact name before its published to a maven repository. This is accomplished by following a similar release process as kafka core, which encodes the Scala major version and then runs the build for each major version of Scala supported. This is considered standard practice when releasing Scala libraries, but is not handled for us automatically with the basic Scala for Gradle support.
After this change you can generate and install the kafka-streams-scala artifact into the local maven repository:
$ ./gradlew -PscalaVersion=2.11 install
$ ./gradlew -PscalaVersion=2.12 install

This pull request is for JIRA 6657, for KIP-276.
Added unit tests for new getGlobalConsumerConfigs API and make sure existing restore consumer tests are passing.

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
$ ./gradlew -Dtest.single=WordCountTest streams:streams-scala:test
```

Closes#4756 from debasishg/scala-streams
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.

In dsi-api.html, when reading from Kafka to a KTable, the doc says "In the case of a KStream.." where `Kstream` here is not correct. They should be `KTable`.
