Update git submodules

* Update devstack from branch 'master'
  - Document the wonders of scale testing nova with the fake driver
    
    Devstack has some little known variables for running nova
    with the fake compute driver and running several nova-compute
    services on a single host, which can be useful for testing
    move operations and scale testing of controller services like
    nova-api and nova-scheduler.
    
    This adds documentation about the fake virt driver and related
    variables and scaling considerations when using them.
