Update git submodules

* Update docs/submodules/yardstick from branch 'master'
  - Merge "ansible: fix urlsplit('hostname') in convert_openrc"
  - ansible: fix urlsplit('hostname') in convert_openrc

    can't use urlsplit|attr('hostname') since urlsplit is a dict

    should instead use urlsplit('hostname')
