Update git submodules

* Update docs/submodules/dovetail from branch 'master'
  - Updating user guide with new ssh key config in pod.yaml
    
    Dovetail does not copy the ssh key from pre_config to /root/.ssh anymore
    inside Yardstick but instead, we point the pod.yaml file directly to the
    key inside the pre_config directory.
