Update git submodules

* Update docs/submodules/yardstick from branch 'master'
  - Merge "Kubernetes NodePort must have 'name' if multiple created"
  - Kubernetes NodePort must have 'name' if multiple created
    
    In Kubernetes context, service NodePort can contain more than one port
    defined. Actually, by default port SSH (22) is always created. If more
    than one port is defined in the service template, 'name' parameter is
    mandatory.
    
    Names must be lowercase, containing alphanumeric characters or '-'.
    
    Verification regex used by Kubernetes: [a-z0-9]([-a-z0-9]*[a-z0-9])?
