Fix clients IPs by trusting the proxy

[Petitoto]

Subject of the issue

We should add a settings to trust X-Forwarded-For header for a specifc proxy. Thus, we would get the real IP addresses of the clients instead of the IP of the proxy.

Your environment

• Version of Hyperion : latest release
• Operating system : debian

Steps to reproduce

Run the server behind a proxy and let clients connect to Hyperion.

Expected behaviour

We should see the clients' IP in the logs.

Actual behaviour

We see the proxy IP address in the logs.
