    Make image conversion use a proper python interpreter for prlimit

    The image conversion plugin does a processutils exec(), which needs
    to spawn python for prlimit support. Under uwsgi, sys.executable
    points to uwsgi itself, which won't work in this case. This introduces
    a [wsgi]/python_interpreter config option (because I don't think
    there is any way to get this from uwsgi itself) which we use for
    the exec. By default, it's sys.executable, which is what is used
    right now so nobody should notice a change unless they need it.

    Note: Making this depend on the devstack change to remove the wsgi
    import restriction so we can get a test on it.
