The get_host() method fails when the host is behind multiple proxies. In some cases,

Browser --> Knox --> Apache Load Balancer --> Hue

Hue Django code receives self.META['HTTP_X_FORWARDED_HOST'] values such as

host1:port1, host2:port2.

This patch accepts self.META['HTTP_X_FORWARDED_HOST'] header and process last tuple as self.META['HTTP_X_FORWARDED_HOST'] value.
