Move images used out of container registry in repo1

Big Bang will be moving the top level group to a new area under repo1. GitLab does not allow projects to be moved with images in the container registry. In addition, Big Bang will be disabling container registries going forward.

1. Identify which images are used in registry.dso.mil for this project
2. Identify alternative sources for images (either IronBank or upstream repos)
3. Make changes to the project to pull from the alternative source.
