docker images for CI

Using Docker images dramastically impact how CI is executed. It is very quick (~10min). I prepared this MR based on the setup from GNOME/glib and created ubuntu-devel image based on the current CI config. I tweaked a little bit the CI file and it works very well. We may add any other images for fedora and debian to get better testing. What we need is to upload a docker image to the register.gnome.org/GNOME/libgda. Before any work, we need to update the TAG variable https://gitlab.gnome.org/pavlosun/libgda/blob/wip/docker-images/.gitlab-ci/run-docker.sh#L88
