    Add http_proxy_to_wsgi to api-paste

    This sets up the HTTPProxyToWSGI middleware in front of Neutron-API. The
    purpose of this 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 Neutron.

    So, for instance, when TLS connections are being terminated in the
    proxy, and one tries to get the versions from the / resource of
    Neutron, one will notice that the protocol is incorrect; It will show
    'http' instead of 'https'. So this middleware handles such cases.
    Thus helping Keystone discovery work correctly.

    The HTTPProxyToWSGI is off by default and needs to be enabled via a
    configuration value.
