Bug description:
When executing the test "test_connectivity_through_2_routers" it is highly
possible to have
a race condition:
networking_ovn.common.exceptions.RevisionConflict: OVN revision number
for {PORT_ID} (type: ports) is equal or higher than the given
resource. Skipping update.

===== Ubuntu SRU Details =====
[Impact]
See bug description.
[Test Case]
Deploy openstack with OVN. Run the test_connectivity_through_2_routers test
from https://github.com/openstack/neutron-tempest-plugin. This could also be
tested manually based on what that test does. Ensure the router port status is
not set to DOWN at any point.
[Where problems could occur]
The existing bug could still occur if the assumpion that specifying the port
type is not correct. Presumably this is not the case, but that is a theoritical
potential for where problems could occur. All of these patches have already
landed in the corresponding upstream branches.
