    Set secure fail mode for physical bridges

    Physical bridges can cause network disruption when ofctl controller becomes
    inaccessible due to heavy load or when the traffic to controller is blocked.
    By setting secure fail mode, the openflow rules remain untouched on such
    an event, while with the default setting, the flows are cleared.
