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.

There were a couple of important issues fixed in Gradle 3.2.1:
* [GRADLE-3582] - Gradle wrapper fails to escape arguments with nested quotes
* [GRADLE-3583] - Newlines in JAVA_OPTS breaks application plugin shell script in Gradle 3.2
And a lot of important issues fixed in Scala 2.12.1:

Closes#2036 from jozi-k/update-rocksdb-4.11.2
rocksdbjni version 4.9.0 now includes support for running on Windows; this PR updates Kafka Stream's dependency to that version. Tests pass locally, except for a timeout in testReprocessingFromScratchAfterReset that doesn't seem related; it happens with and without this change.

Closes#1783 from mfenniak/update-rocksdb-4.9
* The hope is that RocksDb 4.4.1 is more stable than 4.1.0 (occasional segfaults) and 4.2.0 (very frequent segfaults), release notes for 4.4.1: https://www.facebook.com/groups/rocksdb.dev/permalink/925995520832296/
* slf4j 1.7.21 includes thread-safety fixes: http://www.slf4j.org/news.html
* snappy 1.1.2.4 includes performance improvements requested by Spark, which apply to our usage: https://github.com/xerial/snappy-java/blob/master/Milestone.md
I ran the stream tests several times and they passed every time while 4.2.0 segfaulted every time.
