tools/gen-user-data generates a cloud-init user-data file from a
configuration directory. It is mostly useful to embed files in the
user-data.
tools/deploy-qemu uses above tool to make a user-data file and spins up
a virtual machine with it. This is useful to locally run, test, and
debug osbuild-composer.
A simple user-data directory for running tests locally is included in
tests/deploy-user-data. It expects a repository with osbuild-composer
rpms to be served on the host's port 8000.
