Should this be flagged somehow to correspond with the version of Java being used, or maybe intentionally flagged? I believe Samza under Java 8 is still using Hadoop 2.10

I confirmed that using Java8 still works with this setup (meaning 3.3.4). So this whole system still works if you are running Java 8, It's just that this newer setup (if you use Samza 1.8.0) now works with Java 11.

This is preparing things so that this app will work with Java 11. Once this Samza app PR is merged and released, we can update this to use the that version in the pom.xml file.
I am also deleting the gradle artifacts because this whole project is actually using Maven (not gradle, which was version 2 or something).
Verified that these version bumps (including the use of Scala 2.12 from Samza) all work. Note this moves Hadoop to be a Java 11 compatible version as well.
I have also tested with my local build from the Samza PR above, and using Java 11 that all of this works as well.
