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."

This ensures duplicates are not copied in the distribution without rewriting all of the tar'ing logic. A larger improvement could be made to the packaging code, but that should be tracked by another jira.

* Fix and suppress number of unchecked warnings (except for Kafka Streams)
* Add `SafeVarargs` annotation to fix warnings
* Suppress unfixable deprecation warnings
* Replace deprecated by non-deprecated usage where possible
* Avoid reflective calls via structural types in Scala
* Tweak compiler settings for scalac and javac
Once we drop Java 7 and Scala 2.10, we can tweak the compiler settings further so that they warn us about more things.

Adds a gradle task to generate a report of outdate release dependencies:
`gradle dependencyUpdates`
Updates a few minor versions.

Closes#973 from granthenke/outdated-deps
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.

Patch version bumps for bouncy castle, minikdc, snappy, slf4j, scalatest and powermock. Notable fixes:
* Snappy: fixes a resource leak
* Bouncy castle: security fixes
Also update Gradle to 2.11 (where the notable change is improved IDE integration) and the grgit build dependency.

We can take advantage of the fact that major Scala versions are binary compatible (since 2.10) to make the build a little more user-friendly.

More performance improvements:
"In many cases, Gradle 2.9 is much faster than Gradle 2.8 when performing incremental builds.
Very large builds (many thousands of source files) could see incremental build speeds up to 80% faster than 2.7 and up to 40% faster than 2.8.
Gradle now uses a more efficient mechanism to scan the filesystem, making up-to-date checks significantly faster. This improvement is only available when running Gradle with Java 7 or newer.
Other improvements have been made to speed-up include and exclude pattern evaluation; these improvements apply to all supported Java versions.
Gradle now uses much less memory than previous releases when performing incremental builds. By de-duplicating Strings used as file paths in internal caches, and by reducing the overhead of listing classes under test for Java projects, some builds use 30-70% less memory that Gradle 2.8."

Gradle does not handle subprojects with the same name (top-level tools vs
connect/tools) properly, making the dependency impossible to express correctly
since we need to move the ThroughputThrottler class into the top level tools
project. Moving the current set of tools into the runtime jar works fine since
they are only used for system tests at the moment.
