* 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.
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
- adds Streams upgrade tests for 1.1 release

* 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.
* 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.

It's a critical bug that only affects the server, but we
don't have an easy way to use 3.4.11 for the client
only.

* MINOR: Update gradle, jackson and jacoco
- Gradle update adds support for Java 10
- Jacoco update adds support for Java 9
- Jackson bug fix update adds more serialization

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.

Closes#4429 from scholzj/kip-208
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:
https://zookeeper.apache.org/doc/r3.4.11/releasenotes.html
A notable fix is improved handling of UnknownHostException:
https://issues.apache.org/jira/browse/ZOOKEEPER-2614
Manually tested that IntelliJ import and build still works.
Relying on existing test suite otherwise.

- Rename `encode` to `legacyEncodeAsString`, we
can remove this when we remove `ZkUtils`.
- Introduce `encodeAsString` that uses Jackson.
- Change `encodeAsBytes` to use Jackson.
- Avoid intermediate string when converting
Broker to json bytes.
The methods that use Jackson only support
Java collections unlike `legacyEncodeAsString`.
Tests were added `encodeAsString` and
`encodeAsBytes`.

Use slf4j (via scala-logging) instead. Also:
- Log4jController is only initialised if log4j if in the classpath
- Use FATAL marker to support log4j's FATAL level (as the log4j-slf4j bridge does)
- Removed `Logging.swallow` in favour of CoreUtils.swallow, which logs to the
correct logger

Closes#3881 from ijuma/kafka-5884-powermock-java
- EasyMock 3.5 supports Java 9.
- Fixed issues in `testFailedSendRetryLogic` and
`testCreateConnectorAlreadyExists` exposed by new EasyMock
version. The former was passing `anyObject` to
`andReturn`, which doesn't make sense. This was leaving
behind a global `any` matcher, which caused a few issues in
the new version. Fixing this meant that the correlation ids had
to be updated to actually match. The latter was missing a
couple of expectations that the previous version of EasyMock
didn't catch.
- Removed unnecessary PowerMock dependency from 3 tests.
- Disabled remaining PowerMock tests when running with Java 9
until https://github.com/powermock/powermock/issues/783 is
in a release.
- Once we merge this PR, we can enable tests in the Java 9 builds
in Jenkins.

Closes#3791 from andrasbeni/dependency-upgrade
Notable updates:
1. Gradle 4.1 includes a number of performance and
CLI improvements as well as initial Java 9 support.
2. Scala 2.12.3 has substantial compilation time
improvements.
3. lz4-java 1.4 allows us to remove a workaround in
KafkaLZ4BlockInputStream (not done in this PR).
4. snappy-java 1.1.4 improved performance of compression (5%)
and decompression (20%). There was a slight increase in the
compressed size in one of our tests.
Not updated:
1. PowerMock due to a couple of regressions. I investigated one of them
and filed https://github.com/powermock/powermock/issues/828.
2. Jackson, which will be done via #3631.
3. Rocksdb, which will be done via #3519.

Closes#3619 from ijuma/update-deps-for-1.0.0
In a test by onurkaraman involving 3066 topics and 95895 partitions,
Controller initialisation time spent on JSON parsing would be reduced from
37.1 seconds to 0.7 seconds by switching from the current JSON parser to
Jackson. See the following JIRA comment for more details:
https://issues.apache.org/jira/browse/KAFKA-5328?focusedCommentId=16027086
I tested that we only use Jackson methods introduced in 2.0 in the main
codebase by compiling it with the older version locally. We use a
constructor introduced in 2.4 in one test, but I didn't remove it as it
seemed harmless. The reasoning for this is explained in the mailing list
thread:
http://search-hadoop.com/m/uyzND1FWbWw1qUbWe
Finally, this PR only handles the parsing side. It would be good to use Jackson
for serialising to JSON as well. I filed KAFKA-5631 for that.
