0. Minor fixes on the existing examples to merge all on a single input topic; also do not use `common.utils.Exit` as it is for internal usage only.
1. Add the archetype project for the quickstart. Steps to try it out:
a. `mvn install` on the quickstart directory.
b. `mvn archetype:generate \
-DarchetypeGroupId=org.apache.kafka \
-DarchetypeArtifactId=streams-quickstart-java \
-DarchetypeVersion=1.0.0-SNAPSHOT \
-DgroupId=streams-quickstart \
-DartifactId=streams-quickstart \
-Dversion=0.1 \
-Dpackage=StreamsQuickstart \
-DinteractiveMode=false` at any directory to create the project.
c. build the streams jar with version `1.0.0-SNAPSHOT` to local maven repository with `./gradlew installAll`; `cd streams-quickstart; mvn clean package`
d. create the input / output topics, start the console producer and consumer.
e. start the program: `mvn exec:java -Dexec.mainClass=StreamsQuickstart.Pipe/LineSplit/WordCount`.
f. type data on console producer and observe data on console consumer.

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.

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.

**JIRA ticket:** [KAFKA-5081 two versions of jackson-annotations-xxx.jar in distribution tgz](https://issues.apache.org/jira/browse/KAFKA-5081)
**Solutions:**
1. accept this merge request **_OR_**
2. upgrade jackson libraries to version **_2.9.x_** (currently available as a pre-release only)
**Related jackson issue:** [Add explicit \`jackson-annotations\` dependency version for \`jackson-databind\`](https://github.com/FasterXML/jackson-databind/issues/1545)
**Note:** previous (equivalent) merge request #2900 ended up deep in the sand with swarm of messages due to flaky test, so I opted to close it and to open this one.

Also upgrade scoverage (required for compatibility) and remove usage of

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).

This is my first time writing Scala, so let me know if there are any changes needed.

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.

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.

_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.
