Don't pass volumes_from to create_container

Don't pass the volumes_from argument to the Docker create_container method.

If the volumes_from argument is passed to the create_container method, Docker
raises the following exception:

    docker.errors.DockerException: 'volumes_from' parameter has no effect on
    create_container(). It has been moved to start()

Only tested on:

Docker 1.4.1
docker-py 0.7.0
