This commit makes ML snapshot downloading happen less often. It does
that by first moving the download location to a directory outside the
destructive power of gradle clean, and then also uses the md5 of the zip
to compare to that found in s3. This allows us to do a cheap HEAD
request to find if the file has changed.

With Gradle 4.1 and newer JDK versions, we can finally invoke Gradle directly using a JDK9 JAVA_HOME without requiring a JDK8 to "bootstrap" the build. As the thirdPartyAudit task runs within the JVM that Gradle runs in, it needs to be adapted now to be JDK9 aware.

When the machine-learning-cpp repo is built locally, the zip file it
creates is preferred over that downloaded from s3 when creating the
overall x-pack-elasticsearch zip. However, prior to this change the
build would ALSO download an ml-cpp zip from s3, and just not use it.

This commit adds an internal project call ml-cpp-snapshot which when
built will pull the ml cpp zip file from the prelert bucket. The GET
request has retries added to handle the dynamic aws creds eventual
consistency.
