Hi Xavier,
This is the only patch in the series for which I have a recommendation.
The rest all look good to me.

In some rare cases, and despite "recent" changes to wait for cleanup
before replying to exit, ovn-controller was still running when trying

I think this should just be called "OVN_CONTROLLER_RESTART". The goal is
to restart ovn-controller, so I think the simpler name makes sense. It's
true that we are using an "exit" command for ovn-appctl, but that is
more of an implementation detail than anything else.
