CI jobs which build images will include a config file then run the
command to build all images. This means that
overcloud-hardened-images-uefi needs to do the same thing as
overcloud-full, and have the image definition for ironic-python-agent
as well as overcloud-hardened-uefi-full.
Without this change the ironic-python-agent image won't be built and
the CI job will fail.
