sw test tool: pylint

E:1026, 8: Instance of 'DummyDatapath' has no 'set_xid' member (but some types could not be inferred) (maybe-no-member)
E:1027, 8: Instance of 'DummyDatapath' has no 'send_msg' member (but some types could not be inferred) (maybe-no-member)

NOTE: These methods are never called. This patch is only for avoiding pylint error.

sw test tool: Enable sending packets using random values

The switch test tool is now enabled to send packets using random values as follows:

        "tests":[
            {
                "ingress":{
                    "packets":{
                        "data":[
                            "ethernet(dst=netaddr.EUI(randint(0, 2 ** 48 - 1)), ethertype=2048)",
                            "ipv4(proto=6, src=netaddr.IPAddress(randint(0, 2 ** 32 - 1)))",
                            "tcp(dst_port=randint(0, 2 ** 16 - 1))",
                            "str(\"\\x11\" * (1500 - 54))"
                        ],
                        "pktps":1000,
                        "duration_time":30
                    }
                },
                "egress":{
                    "throughput":[
                        {
                            "OFPMatch":{
                                "oxm_fields":[
                                    {
                                        "OXMTlv":{
                                            "field":"in_port",
                                            "value":2
                                        }
                                    }
                                ]
                            },
                            "kbps":1500
                        }
                    ]
                }
            }
        ]

When ingress.packets.data includes 'randint', the switch test tool will send each packet using random values.
