[Winson Chan]

Gunicorn requires the wsgi module to have application variable setup. The change made support Apache assumes the wsgi module is executed as script and breaks Gunicorn setup for the API.

    Fix WSGI script for gunicorn

    The previous patch to add support for apache breaks gunicorn. The gunicorn
    setup loads the mistral.api.wsgi module and requires the application
    variable be assigned. The support for apache make the assumption that the
    mistral.api.wsgi be called as a python script. This patch moves the init
    function required by apache to a different location.
