Refactored SeedProvider and Updated Docker

This is a redo of the last PR that I munged 😄 

- fixed maven build folder structure
- updated build to C* 3.4
- refactored Seed Provider - improved error handling, updated default SeedProvider code
- added start of unit tests.  Not as comprehensive as I would like
- updated docker image to debian:jessie
- installed openjdk 8
- added some docker fu to make the image smaller
- updated docker to C* 3.4 and update yaml
- updated README content.  Added a section about the docker, and the SeedProvider

Have not had a chance to test the docker on k8s, because I do not have a local docker repo.

NOTE: someone needs to push the docker image into the google repo. Not sure what the process is ...  I will submit another PR request with changes to the yaml files.
