Comment 5 for bug 1605089

@Richard, I think create and delete may not be a real issue because:

Create - before it complete and returns the client can't get the handle (uuid) thus would not initiate a conflicting operation for that object.

Delete - if the order is messed up with other operations, we would simply get an error from OVN IDL complaining that "object not exist", but won't result in inconsistent state between neutron and ovn.
