Update git submodules

* Update docs/submodules/functest from branch 'stable/fraser'
  - Switch create_server timeout to default value

    60s was successfully reached when running all containers (3
    containers * 3 branches) in parallel.

    It also removes the wait attribute (the current impl will meet
    a possible next asynchronous design) which is useless here.

    For the time being, only cloudify needs an extra timeout.
