feat: Add bootc support (#448)

Adds support for using `bootc` as the preferred method for booting from
a locally created image. This new method gets rid of the need to create
a tarball and move it to the correct place and instead it will make use
of `podman scp` which copies the image to the root `containers-storage`
and then has `rpm-ostree` and `bootc` boot from that store.

Closes #418 
Closes #200
