    Add CORS and HTTPProxyToWSGI support based on oslo_middleware in front
    of the Qinling API. The purpose of this middleware is to set up the
    request URL correctly in the case there is a proxy (for instance, a
    loadbalancer such as HAProxy) in front of the Qinling API.
    The HTTPProxyToWSGI is off by default and needs to be enabled via a
    configuration value.
