This adds a test for this invariant for a specific test case, which is
useful. However, I believe that this should be a universal invariant
for ovn-controller, so that at any time if ovn-controller is restarted
gracefully after it has converged, it should preserve these flows. Is
that true? If so, then it would be more useful to add such a check to
*every* test case for OVN.
What do you think?
Thanks,
Ben.
