Update git submodules

* Update docs/submodules/yardstick from branch 'master'
  - Merge "resource: remove cores args"
  - resource: remove cores args
    
    We used to try to probe all the cores that the VNF was using
    and only dump CPU stats for those cores.
    
    We can't really detect those core accurately and we would rather
    dump all the core information and let influxdb and grafana filter
    the information.
    
    We do end up with excessive KPI output, especially on systems with 88
    cores, but this is manageable.
    
    The core logic was partially removed, this finishes the removal.
