  - Add service in kubernetes context

    JIRA: YARDSTICK-803

    Currently kubernetes test case can only run in master node.

    We need to support it run in jump server.
    So I add service and use nodePort type.

    Then we can login the pod using nodePort.

  - tg_rfc2544_ixia: use traffic id from JSON to update mac

    we were using raw sort index of the interfaces to
    set the MAC address, but we should be using the
    traffic id from the static JSON instead.

  - prox: fix TG KPIs

    The problem is that we share the same ProxResourceHelper
    for both VNF and TG.

    For VNF we want to talk to resource.py and get collectd KPIs.
    For TG we need to read from the queue the TG calculated KPIs and
    we also want collectd KPIs.

    workaround is to use a different method name collect_collectd_kpi
    for VNFs

  - Heat: use pkey from string instead of key_filename

    Instead of using a key_filename for Heat, we can
    read the key as a string directly using pkg_resources.resource_string()

    This will enable us to save Heat stacks as pod.yaml, because
    we can embedded the key into the pod.yaml directly.
