Update git submodules

* Update docs/submodules/yardstick from branch 'master'
  - Merge "Add "securityContext" parameter in Kubernetes context"
  - Add "securityContext" parameter in Kubernetes context
    
    This new parameter, "securityContext", will allow the user to define the
    privilege and access control settings for a pod or a container [1].
    
    Example of "securityContext" definition in the pod (if only one container
    is defined):
    
      context:
        type: Kubernetes
        servers:
          host:
            image: ...
            securityContext:
              runAsUser: 1000
              fsGroup: 2000 
    
    Example of "securityContext" definition in the pod and the container (if
    several containers are defined):     
    
      context:
        type: Kubernetes
        servers:
          host:
            securityContext:
              runAsUser: 1000
              fsGroup: 2000 
            containers:
              - image: ...
                securityContext:
                  allowPrivilegeEscalation: false
              - image: ...
