gitlab: introduce CI jobs testing git master & distro libvirt

The python build needs to validate two axis

 - A variety of libvirt versions
 - A variety of python versions

We get coverage for both these axis by running a build against the
distro provided libvirt packages. All that is then missing is a build
against the latest libvirt git master, which only needs to be run on
a single distro, for which CentOS 8 is picked as a stable long life
base.

+CI job assets
+=============
+
+This directory contains assets used in the automated CI jobs, most
+notably the Dockerfiles used to build container images in which the
+CI jobs then run.
+
+The ``refresh`` script is used to re-create the Dockerfiles using the
+``lcitool`` command that is provided by repo
+https://gitlab.com/libvirt/libvirt-ci
+
+The containers are built during the CI process and cached in the GitLab
+container registry of the project doing the build. The cached containers
+can be deleted at any time and will be correctly rebuilt.
