Update git submodules

* Update docs/submodules/yardstick from branch 'master'
  - Merge "Add host&targer in scenario['options']['server_name'] support"
  - Add host&targer in scenario['options']['server_name'] support

    JIRA: YARDSTICK-810

    Currently host, target is in scenario, but as a input, we prefer it in
    scenario['options'].
    So I add support for under scenario['options']['server_name']

    If we write host in scenario['options']['server_name'], the host ip info
    will be written in context.
