We suspect that the test suite hangs we have been seeing are
due to PermGen exhaustion. It is a common reason for
hard JVM lock-ups.

Closes#1926 from ijuma/test-jvm-params
Also upgrade scoverage (required for compatibility) and remove usage of
`useAnt` which doesn't exist in Gradle 3.0
It turns out that one cannot even run `gradle` to download the project Gradle version if `useAnt` is used in the build. This is unfortunate (the SBT launcher has much saner behaviour).

Closes#1774 from ijuma/kafka-4082-support-gradle-3.0
ijuma said that it would make sense to split out this work from KAFKA-3234, since KAFKA-3234 had both a mechanical change (generating docs) as well as a change requiring discussion (deprecating/renaming config options).
jjkoshy, I hope you don't mind that I took over this work. It's been 3 months since the last activity on KAFKA-3234, so I thought it would be okay to take over.
This work is essentially is the first 5-6 commits from Joel's https://github.com/apache/kafka/pull/907. However, since I'm not very experienced with git, I didn't do a direct merge/rebase, but instead largely hand-merged it. I did some minor cleanup. All credit goes to Joel, all blame goes to me. :)
For reference, I attached the auto-generated configuration.html file (as a PDF, because github won't let me attache html).
[configuration.pdf](https://github.com/apache/kafka/files/323901/configuration.pdf)
This is my first time writing Scala, so let me know if there are any changes needed.
I don't know who is the right person to review this. ijuma, can you help me redirect this to the appropriate person? Thanks.

This is a regression caused by 0bb1d3ae.
After that commit, Streams no longer has a direct dependency on slf4j-log4j12, but zkclient
has a dependency on an older version of slf4j-log4j12, so we get a transitive dependency on
the older version.
The fix is to simply exclude the undesired dependencies from the zkclient dependency.

Closes#1644 from ijuma/update-gradle
As kafka-streams is intended to be used by applications that may or may not wish to use log4j, kafka-streams itself should not have a dependency on a concrete log framework. This change adapts the dependencies to be API-only for compile, and framework-specific for the test runtime only.
I read through the [Contributing Code Guidelines](https://cwiki.apache.org/confluence/display/KAFKA/Contributing+Code+Changes) and interpreted this as a trivial change that doesn't require a Jira ticket. Please let me know if I've interpreted that wrongly.
This contribution is my original work and I license the work to the project under the project's open source license.

These dependencies are unnecessary and they are acquired
transitively via zkclient (jline, netty) and reflections (annotations).
Ewen did the hard work in figuring out why we have unexpected
additional dependencies since 0.9.x.

_copyDependantTestLibs_ was added temporarily as a dependency of _jar_ task to enable SASL system tests to be run with MiniKdc without changing the automated system test runs which run _gradlew clean jar_. Since the build target _systemTestLibs_ is already in Kafka build.gradle, the Confluent automated test runs can now run _gradlew clean systemTestLibs_ instead. This PR provides the final change to remove _copyDependantTestLibs_ from the _jar_ task. This should be committed only after the Confluent automated sytem test build script is updated, to avoid breaking any builds.

There are a few improvements in 2.12 and 2.13. I am particularly interested in the performance improvements:
* 2.12: "This release brings support for compile only dependencies, improved build script compilation speed and even better IDE support."
* 2.13: "We've achieved performance improvements during Gradle's configuration and execution phase, where we have measured up to 25% improvements to build time in our performance tests. No changes to your build script are necessary to start taking advantage of these improvements."

* Add `SafeVarargs` annotation to fix warnings

Without this change `./gradlew releaseTarGz` (and its variants) will not include the RocksDB jar, which is required for Kafka Streams, in Kafka's `libs/` folder. The impact is that any Streams job will fail when it runs against a broker that was installed via a release tarball.
