* 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.

* MINOR: Update gradle, jackson and jacoco
- Gradle update adds support for Java 10

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.
Manually verified that there are no duplicate dependencies
in the release tarball and `./gradlew core:dependencies`
looks good.

correct logger

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.

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.

CLI improvements as well as initial Java 9 support.
2. Scala 2.12.3 has substantial compilation time
improvements.

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.

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.
