    Add http_proxy_to_wsgi to api-paste
    
    This sets up the HTTPProxyToWSGI middleware in front of Searchlight.
    The purpose of thise middleware is to set up the request URL correctly
    in case there is a proxy (For instance, a loadbalancer such as HAProxy)
    in front of Searchlight.
    
    So, for instance, when TLS connections are being terminated in the
    proxy, and one tries to get the versions from the / resource of
    Searchlight, one will notice that the protocol is incorrect; It will
    show 'http' instead of 'https'. So this middleware handles such cases.
    
    The HTTPProxyToWSGI is off by default and needs to be enabled via a
    configuration value.

Bug description:
  It's a common problem when putting a service behind a load balancer to
  need to forward the Protocol and hosts of the original request so that
  the receiving service can construct URLs to the loadbalancer and not
  the private worker node.

  Most services have implemented some form of secure_proxy_ssl_header =
  HTTP_X_FORWARDED_PROTO handling however exactly how this is done is
  dependent on the service.

  oslo.middleware provides the http_proxy_to_wsgi middleware that
  handles these headers and the newer RFC7239 forwarding header and
  completely hides the problem from the service.

  This middleware should be adopted by all services in preference to
  their own HTTP_X_FORWARDED_PROTO handling.
