Bb 680 k3d fresh install and upgrade

What:

• Adds a new job that tests new changes on a given branch as an upgrade from master not just a fresh install
• Cleans up some of the .gitlab-ci code

Why:

• End customers will most likely not be doing a fresh install of the cluster everytime a new package is released, this starts to try and test that upgrade.
