add .gitlab-ci-coverage.yml for a scheduled build

This will be used by the https://gitlab.com/samba-team/samba
configuration, while https://gitlab.com/samba-team/devel/samba
will still use .gitlab-ci.yml (via the legacy .gitlab-ci-private.yml).

The key point is the usage of the more powerful n1-standard-2
runners for testing.
