    [OVS] Exception message when retrieving bridge-id and is not present

    In the OVS agent, when setting up the ancillary bridges, the parameter
    external_id:bridge-id is retrieved. If this parameter is not defined
    (e.g.: manually created bridges), ovsdbapp writes an error in the logs.
    This information is irrelevant and can cause confusion during debugging time.
