plugins: Add bootc provision plugin

This creates a new provision plugin that is built on top of the existing
TestCloud (virtual) plugin. It adds new parameters to pass a
Containerfile or container image. The plugin will then build a container
image (if necessary) then build a bootc disk image from the container
image using bootc image builder. Currently, bootc requires podman to be
run as root when building a disk image. This is typically handled by
running a podman machine as root.

An additional parameter "add-deps" toggles building a derived container
image with the tmt test requirements.
