Adds a ``bootc`` deployment interface which can be enabled to
perform deployment of bootable containers. This enables a streamlined
workflow where an operator/user can push container updates and does not
need to build intermediate disk images and then post those disk images
to facilitate the deployment of a bare metal node.
