    [OVN] The OVS IDL connection is global for all tests
    
    In the functional tests, the OVN databases are created per test and
    removed at the end. That leaves no trace the local OVN databases if
    running in a system running OpenStack. But the OVS database is global
    and shared with all the tests and running processes. It is needed to
    use the OVS IDL ``api_factory`` method that returns a global object
    for all tests.
