Multinode tests are scheduled every day by CI, but only on main.

Multinode tests are never scheduled on branches such as ovn-24.03.

However, multinode tests can also detect issues created e.g. by backports, so it would be nice to also run those tests on supported releases such as 24.03, 24.09, 25.03, 25.09. 

Those could run e.g. once a week.
