Add a test that performs typical operations of creating & destroying logical routers, switches, ports, address sets and ACLs while checking if they trigger full logical flow processing in the ovn-controller. This way confirm that incremental processing is taking effect when we expect it to.
Place the new test in a separate module - tests/ovn-performance.at, instead of the usual tests/ovn.at as it doesn't test OVN's functionality but rather a performance aspect of ovn-controller.
