Kubernetes Launch Script Functionality Improvement
Changed the way this script handles being called upon so that it can
support more than just the build-setup.sh. It will now call a
templated YAML file. This template will be filled out and launched via
kubectl. A case check will be used to set the default variables that are
needed by the specific invoker. To satisfy these changes updated the
build-setup.sh, added a templates folder, and added two templates for
the build-setup.sh script.
