I pushed this version to the main branch.

However, it's still not 100% clear to me if there are other upgrade
related issues we should address on top of it.

Frode, does this change, which introduces and uses a new action
unconditionally in ovn-northd, affect upgrade scenarios in your deployments?

Upgrading ovn-controllers first and then central components should work
fine.

Upgrading in any order with ovn-match-northd-version set on all chassis
should also not disrupt existing flows.

As a final fail safe we could also backport the feature flag bits that
Ales added in v5 [0].  But I'd prefer not doing that if not really needed.

Looking forward to your feedback!

Thanks,
Dumitru
