[libvirt-jenkins-ci PATCH 3/5] guests: Introduce the new 'gitlab' flavor

With the recent efforts in upstream libvirt to centralize our CI on gitlab, let's add a new gitlab-specific flavor along with related playbook tasks. This flavour revolves around installing and configuring the gitlab-runner agent binary which requires the per-project registration token to be specified in order for the runner to be successfully registered with the gitlab server. Note that as part of the registration process each runner acquires a new unique access token. This means that we must ensure that the registration is run only on the first update, otherwise a new runner with a new access token is registered with the gitlab project.
