Rework jobs/playbooks/roles
Current setup doesn't work that well when inheriting. I would like "all
my projects" to only inherit from the job which uses the
`run-test-command` playbook. Then, those jobs which need submodules,
should explicitly ask for that pre- playbook provided by
`git-submodules`.
In Zuul and Ansible, roles are the bits that are supposed to be shared.
As per corvus recommendation on IRC, let's use job variables to control
execution in a more fine-grained manner.
