Hi Han,

Thanks for working on fixing this!  I wonder however if there will be
any performance impact due to the added resource references?  I didn't
do any scale testing, did you have a chance to?

As an alternative, maybe longer term though, would it make sense to use
explicit references instead in the Southbound schema?  That would
simplify the ovn-controller code and would rely on the IDL to propagate
the change tracking to the flows that refer to multicast groups/port
bindings/port groups.
