Update git submodules

* Update docs/submodules/yardstick from branch 'stable/fraser'
  - Merge changes from topic 'prox-stable/fraser' into stable/fraser
    
    * changes:
      NSB NFVi PROX BNG losing many packets
      NSB NFVi PROX VPE losing many packets
      Decrease Sampling interval
      Addition of Configurable Sampling and Configurable Confirmation Retry
    
  - NSB NFVi PROX BNG losing many packets
    
    JIRA: YARDSTICK-1101
    
    Problem was incorrect generator and changed the traffic profile to allow
    a tolerated loss of 5%.
    
    ARP packets are not managed (just passed thru the system) therefor the
    tolerated loss must be higehr than normal.

  - NSB NFVi PROX VPE losing many packets
    
    JIRA: YARDSTICK-1105
    
    Running a vPE test ends up with up to 25% drooped packets.
    This is due to tolerated loss being incorrectly configured,
    test duration was too short and test interval was too
    short.
    
    Note This is due to the fact that vPE use case have by
    default a tolerated loss of 100%, Now changed to 0.001,
    same as L2FWD
    
    Also: Grafan dashboard has been updated to show all SUT
    CPUS Utilization in 1 panel. And LINE rate MIN, MAX & TEST
    Rate have been added

  - Decrease Sampling interval
    
    JIRA: YARDSTICK-1219
    
    Currently NSB for NFVI using PROX returns sampling information every 13
    seconds.
    
    This is too slow.
    
    It is required to return sampling information form Generator AND VNF at
    least every  1 second.
    
    This change is depandant on JIRA: YARDSTICK-1212 and YARDSTICK-1220

  - Addition of Configurable Sampling and Configurable Confirmation Retry
    
    JIRA: YARDSTICK-1221
    
    In order to increase accuracy of result the following are done :-
      - Improve Measurement Accuracy (YARDSTICK-1212)
      - Improve Sampling Interval (YARDSTICK-1219)
      - Allow 4 PROX ports to be read simultaneously (YARDSTICK-1220)
    
    This change does the following :-
      - Stores LINE Rate statistics of Sample
      - Requires a confirmation retry before deciding to increase or
        decrease this is configurable.
      - Allows the user to disable Sampling or specify a sample interval
      - Added Code Coverage of ProxDurationRunner based on YARDSTICK-1199
