Bug Description

Test tempest.scenario.test_network_basic_ops.TestNetworkBasicOps.test_preserve_preexisting_port failed with what appears to be an issue in the OVN ML2 driver. According to Terry, "it looks like the create_lrouter call in impl_idl_ovn.py passes may_exist, but the one in ovn_client.py which you are hitting does not."
