[RFC PATCH 10/16] gitlab-ci: Introduce the CI "job maintainer" concept

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

When a job fails, someone has to take care of it. As we can
not wait indefinitively of volunteers good will, introduce the
concept of "job maintainers". A job maintainer is reponsible
of keeping it working, or contact the developers having broken
it to fix it.

When a job is added, it must have a maintainer. A job without
maintainer is not run automatically. It can however be run
manually from the WebUI.

To declare a maintainer, it is as easy as defining the
JOB_MAINTAINER_NAME / JOB_MAINTAINER_EMAIL environment variables.

Ideally the runner will notify the maintainer by mail that
a job fails. But we are not quite there yet.

It would be nice if someone document this properly.
