Major refactor

This is a major refactor of how the CoreOS k8s cluster build process works. Lots of changes including

• #13 (closed)
• Part of #4 (closed) (Adds keys for both the core and root user)
• Part of #16 (closed) - The "infrastructure-daemon" doesn't yet exist, but the controlplane01 autoinstall FCC deploys the init-container.yml manifest from https://gitlab.com/c2-games/scoring/k8s-init-container/
