Add source for osbuild-deploy-container command

[achilleas-k]

Partially replaces #5.

This PR adds the source code for the osbuild-deploy-container command, which up until now was only available in a branch on my fork of the images repository.

It depends on some open PRs in the osbuild/images repository for now.

Depends on:

• Add support for building images from ostree containers images#272
• Make dnfjson module public images#274

Since we have no intentions of pushing this to RHEL for now, what if we don't vendor? We can always start if we need to.

Sure, we can drop the vendoring. I imagine that might make builds a bit slower (and annoying when rebuilding locally) since after cloning the repo and starting the container build, it will have to fetch all the dependencies inside the container.

Noticed a couple of other issues here:

• We need to get dnf-json from images or osbuild (we should actually start using the new packaged version from osbuild).
• The Containerfile doesn't copy the sources into the builder.

That's true. 🤔 Not sure if this trade-off is worth it.

Easy to fix if it gets annoying.

This is ready now.
