This builds a container image containing the DCO checking script. It is then published at: registry.gitlab.com/libvirt/libvirt-jenkins-ci/check-dco:master from where it can be used in all other project repositories. This avoids having to copy the check-dco.py script into every repo when we want to make changes to it. Signed-off-by: Daniel P.
