[FT] BaseOVSTestCase retrieving the wrong min BW queue/qos

[Rodolfo Alonso]

Test case "test_get_egress_min_bw_for_port" is failing retrieving the port min BW queue/qos. According to the report, looks like the test case is retrieving the min BW queue/qos from other test (that should not be possible because the OVS "_min_bw_qos_id" and the port ID are different).

    Check there are no min BW QoS in "BaseOVSTestCase"

    This patche adds a check in "BaseOVSTestCase" setUp method. Each
    time a test is executed, the test case checks there are no
    minimum bandwidth QoS/queues related to this OVS instance. The OVS
    instance generates a random "_min_bw_qos_id" in the initialization.
    This ID is assigned to the OVS QoS registers, in "external_ids:id".
