Join in the Scala streams API is currently unusable in 2.0.0 as reported by @mowczare:
#5019 (comment)
This due to an overload of it with the same signature in the first curried parameter.

* Updated TestLogCleaning tool to use Java consumer and rename as LogCompactionTester.
* Enabled the log cleaner in every system test.
* Removed configs from "kafka.properties" with default values and `socket.receive.buffer.bytes`
as the override did not seem necessary.
* Updated `kafka.py` logic to handle duplicates between `kafka.properties` and `server_prop_overrides`.
* Updated Gradle build so that classes from `kafka-clients` test jar can be used in
system tests.

Relative paths in Gradle break when the Gradle daemon is used
unless user.dir can be changed while the process is running.
Java 11 disallows this, so we use project paths instead.
Verified that rat and checkstyle work with Java 11 after these
changes.

#5468 introduced a breaking API change that was actually avoidable. This PR re-introduces the old API as deprecated and alters the API introduced by #5468 to be consistent with the other methods
also, fixed misc syntax problems
In AK's documentation, the config props for connectors are not listed (https://kafka.apache.org/documentation/#connectconfigs). This PR adds these sink and source connector configs to the html site-docs.

Implementation of [KIP-174](https://cwiki.apache.org/confluence/display/KAFKA/KIP-174+-+Deprecate+and+remove+internal+converter+configs+in+WorkerConfig)
Configuration properties 'internal.key.converter' and 'internal.value.converter'
are deprecated, and default to org.apache.kafka.connect.json.JsonConverter.
Warnings are logged if values are specified for either, or if properties that
appear to configure instances of internal converters (i.e., ones prefixed with
either 'internal.key.converter.' or 'internal.value.converter.') are given.
The property 'schemas.enable' is also defaulted to false for internal
JsonConverter instances (both for keys and values) if it isn't specified.
Documentation and code have also been updated with deprecation notices and
annotations, respectively.
Unit tests have been updated in `PluginsTest` to account for the new defaults for `schemas.enable` for internal key/value converters, and to ensure that (for the time being), internal key/value converters are still configurable despite being deprecated.

This KIP adds the following functionality related to SASL/OAUTHBEARER:
1) Allow clients (both brokers when SASL/OAUTHBEARER is the inter-broker protocol as well as non-broker clients) to flexibly retrieve an access token from an OAuth 2 authorization server based on the declaration of a custom login CallbackHandler implementation and have that access token transparently and automatically transmitted to a broker for authentication.
2) Allow brokers to flexibly validate provided access tokens when a client establishes a connection based on the declaration of a custom SASL Server CallbackHandler implementation.
3) Provide implementations of the above retrieval and validation features based on an unsecured JSON Web Token that function out-of-the-box with minimal configuration required (i.e. implementations of the two types of callback handlers mentioned above will be used by default with no need to explicitly declare them).
4) Allow clients (both brokers when SASL/OAUTHBEARER is the inter-broker protocol as well as non-broker clients) to transparently retrieve a new access token in the background before the existing access token expires in case the client has to open new connections.
* Set --source, --target and --release to 1.8.
* Build Scala 2.12 by default.
* Remove some conditionals in the build file now that Java 8
is the minimum version.
* Bump the version of Jetty, Jersey and Checkstyle (the newer
versions require Java 8).
* Fixed issues uncovered by the new version if Checkstyle.
* A couple of minor updates to handle an incompatible source
change in the new version of Jetty.
* Add dependency to jersey-hk2 to fix failing tests caused
by Jersey upgrade.
* Update release script to use Java 8 and to take into account
that Scala 2.12 is now built by default.
* While we're at it, bump the version of Gradle, Gradle plugins,
ScalaLogging, JMH and apache directory api.
* Minor documentation updates including the readme and upgrade
notes. A number of Streams Java 7 examples can be removed
subsequently.
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
Reviewers: Ismael Juma <ismael@juma.me.uk>, Guozhang Wang <wangguoz@gmail.com>
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

* Upgrade EasyMock to 3.6 which adds support for Java 10
by upgrading to ASM 6.1.1.
* Ensure that Jacoco is truly disabled for the `core` project.
This was the original intent, since it's in Scala, but it had not
been achieved. This is important because the Jacoco agent
fails when it tries to instrument the classes compiled by
scalac with Java 10.
https://github.com/apache/kafka/pull/4760 unintentionally included extra raw class files in the release tarballs by making the .class file output (instead of the jar) for a streams a dependency of the streams-test-utils. This fixes that issue by instead breaking the circular dependency by using a `compileOnly`/`provided` dependency on those sources and also including the dependency as a test dependency.
I verified by using `gradlew clean installAll releaseTarGzAll`, then checking that the release tarball doesn't have the extraneous files and the installed pom file has the expected dependencies. The dependency on kafka-streams is now in the `test` scope, but that should be fine since a streams application would only use this dependency if it already had a dependency on streams in `compile` (or in weird edge cases the user could handle specifying the right dependencies). This actually seems to even be an improvement over the previous situation where the actual dependency was not expressed in the pom at all (since the dependency was on the sourceSet output rather than the actual project).

Closes#4816 from ewencp/fix-streams-dependencies
* Added dependencies so that Trogdor and Connect work with Java 9 and 10
* Updated Jacoco to 0.8.1 so that it works with Java 10
* Updated Gradle to 4.6
* A few minor version bumps (not related to Java9/10 fixes)
I tested manually that we can run ./gradlew test with Java 10
after these changes. There are test failures as EasyMock
and PowerMock will have to be updated to use a newer
ASM version. But compiling successfully and most tests
passing is progress. :)
I also tested manually that Trogdor can be started with Java 10.
It previously failed with a ClassNotFoundError.

This PR implements the JIRA issue [KAFKA-4029: SSL support for Connect REST API](https://issues.apache.org/jira/browse/KAFKA-4029) / [KIP-208](https://cwiki.apache.org/confluence/display/KAFKA/KIP-208%3A+Add+SSL+support+to+Kafka+Connect+REST+interface).
Summary of the main changes:
- Jetty `HttpClient` is used as HTTP client instead of the one shipped with Java. That allows to keep the SSL configuration for Server and Client be in single place (both use the Jetty `SslContextFactory`). It also has much richer configuration than the JDK client (it is easier to configure things such as supported cipher suites etc.).
- The `RestServer` class has been broker into 3 parts. `RestServer` contains the server it self. `RestClient` contains the HTTP client used for forwarding requests etc. and `SSLUtils` contain some helper classes for configuring SSL. One of the reasons for this was Findbugs complaining about the class complexity.
- A new method `valuesWithPrefixAllOrNothing` has been added to `AbstractConfig` to make it easier to handle the situation that we want to use either only the prefixed SSL options or only the non-prefixed. But not mixed them.

Updates:
- Gradle, gradle plugins and maven artifact updated
- Bug fix updates for ZooKeeper, Jackson, EasyMock and Snappy
Not updated:
- RocksDB as it often causes issues, so better done separately
- args4j as our test coverage is weak and the update was a
feature release
Also fixed scala-reflect version to match scala-library.
Release notes for ZooKeeper 3.4.11:

It should only depend on slf4j-api (like kafka-clients). The
release tarball still includes log4j and slf4j-log4j12.

in the release tarball and `./gradlew core:dependencies`
looks good.

Closes#4117 from ijuma/dependency-check
A new mechanism was added recently to the Metrics framework to make it easier to generate the documentation. It uses a registry with a MetricsNameTemplate for each metric, and then those templates are used when creating the actual metrics. The metrics framework provides utilities that can generate the HTML documentation from the registry of templates.
This change moves the recently-added Connect metrics over to use these templates and to then generate the metric documentation for Connect.
This PR is based upon #3975 and can be rebased once that has been merged.
