Similar to what is already done with DISTRO, which points to given image
of ours based on name. This time we do the same with upstream images,
such as debian:stretch or centos:centos8.
This way, for instance calling docker_images_require
"osmo-bsc-latest-centos8" would try to build the
osmo-bsc-latest/Dockerfile file starting from a centos8 image.

This is initialized to docker.io, keeping the default behaviour
if not specified. However, it allows us to specify a private
registry later on.
