Allow docker-java to specify node

Allow {project-name}-{stream}-docker-java-version-shell-daily
to allow a specific build-node to be able to run these
jobs using the ARM architecture nodes.

All current projects using this job will stay unchaged and
will still run their builds on ubuntu1604-docker-8c-8g.
