Please,
if you are adding new images to
fedorainfracloud.org then add those images to playbook
too:
https://infrastructure.fedoraproject.org/cgit/ansible.git/tree/playbooks/...
It is not needed for special playbooks (e.g. copr-builders) but it should be done for
common images (i.e.,
Fedora-Cloud-Base-27-1.6.x86_64.qcow2)
