this patch try to fix two issues:
1.nodeState interface in OpenStackNodeManager should verify wether the INTEGRATION_BRIDGE is created. otherwise, if there is a bridge that is not br-int name,but the same as the dip you configured, if this kind of bridge connected to onos, the nodeState will reture DEVICE_CREATED state, this is not right, it will lead to stuck here beacause createTunnelInterface couldn't work.
2.nodeByDeviceId interface in OpenStackNodeManager should consider when the type of device is CONTROLLER.
