Update git submodules

* Update docs/submodules/yardstick from branch 'stable/danube'
  - Imporve monitor_process pass criteria
    
    JIRA: YARDSTICK-660
    
    The monitor func()'s criteria in the monitor_process.py now is whether at least
    one process of the specific controller node service is recovered. But in reality
    is more resonable to use whether processes have been recoverd to it's original
    amount. This patch is aiming at improving the isssue
