CENTRIFUGO_PROXY parameter

[tboulogne]

For now, could not use django-instant behind a proxy without redirecting centrifugo port.

With this parameter, if CENTRIFUGO_PROXY is True in application.settings, CENTRIFUGO_PORT will be removed from CENTRIFUGO_URL.

Upstream server (example for Nginx will manage port redirection)

CENTRIFUGO_PROXY default is False
