    Pass launch metadata as enviroment variables
    
    The launch metadata is provided with 'nova boot' and
    serves effectively to pass varibles into an instance. This
    runtime key-value pairing seems to map cleanly to environment
    variables as used by Docker. Use of environment variables
    is highly desired amongst nova-docker users and this seems to
    be the cleanest solution to deliver this feature.
