    ci: Add EXTRA_TESTS custom pipeline variable
    
    This variable can be set in scheduled pipelines and when manually
    starting pipelines. When set to `openqa` it causes the
    iso-installer-x86_64 and test-iso-installer-x86_64 jobs to run
    by default, providing a one-step method to trigger an OpenQA test
    cycle.
    
    This is a big improvement on the current method which can take
    several hours and involves: (1) waiting for 'track' and 'build' to
    complete, (2) starting 'iso-installer-x86_64' manually, (3) waiting for
    that to complete, (4) finally, starting 'test-iso-installer-x86_64'.
    
    Fixes https://gitlab.gnome.org/GNOME/gnome-build-meta/-/issues/517
