Update git submodules

* Update docs/submodules/functest from branch 'master'
  - Allow overriding the default role
    
    It allows testing controllers which implements other RBAC policies.
    Defining NEW_USER_ROLE=admin will easily raise side effects for
    orchestrators such as Juju and Cloudify.
