Update git submodules

* Update docs/submodules/yardstick from branch 'master'
  - Merge "Heat: use pkey from string instead of key_filename"
  - Heat: use pkey from string instead of key_filename
    
    Instead of using a key_filename for Heat, we can
    read the key as a string directly using pkg_resources.resource_string()
    
    This will enable us to save Heat stacks as pod.yaml, because
    we can embedded the key into the pod.yaml directly.
