* Update docs/submodules/yardstick from branch 'master'
  - Merge "Yardstick real-time influxdb KPI reporting regressions"
  - Yardstick real-time influxdb KPI reporting regressions
    
    JIRA: YARDSTICK-989
    
    We used to have real-time influxdb reporting of test KPIs. The user
    could monitor using grafana and see the real-time output.
    The record format was changed to now only report KPIs at the end of the
    test.
    This is a problem for test cases which run for a long duration,  we need
    to wait until the end of the test execution to get any results from
    influxdb. If the test fails in between or doesn't exit cleanly for some
    reason, we are left with no results stored in influxdb which gives the
    user no information.
    This is also a regression from the previous behaviour.
