* Update docs/submodules/yardstick from branch 'master'
  - Merge "Parse "dispatcher" options correctly from InfluxDB client"
  - Parse "dispatcher" options correctly from InfluxDB client

    The InfluxDB client needs first to retrieve which dispatchers
    are available from "DEFAULT:dispatcher". This parameter accepts
    comma separated values. "get_data_db_client" method needs to search
    for "influxdb" in this string parameter.
