Update git submodules

* Update docs/submodules/yardstick from branch 'stable/fraser'
  - Merge "Add "os_cloud_config" as a new context flag parameter" into stable/fraser
  - Add "os_cloud_config" as a new context flag parameter
    
    This new parameter will contain the OpenStack cloud specific configuration
    used by Shade client. This new flag is used only in Heat context.
    
    By default, this new parameter (dict) will contain this content:
      'os_cloud_config': {'verify': False}
    
    This field will be used by HeatStack [1] to create a Shade cloud. Shade
    retrieves, if not defined, the OpenStack configuration from
    "os_client_config". This configuration is used to generate the cloud
    configuration, which is the description of the OpenStackCloud returned.
    
    The default parameter defined, "verify", refers to the related bug. By
    default, in case of using SSL certificate it will not be verified.
