Add http_proxy_to_wsgi to api-paste
This sets up the HTTPProxyToWSGI middleware in front of Ceilometer. 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 Ceilometer. So, for instance, when TLS connections are being terminated in the proxy, and one tries to get the versions from the / resource of Ceilometer, 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.
