Proxy Protocol implementation never uses http2 (nginx)

short description

Enabling the proxy protocol disables http/2 mode

correct behaviour

Proxy Protocol should also serve the website as http/2 instead of http/1.1

environment

Webserver: NGINX

ISPConfig version: 3.2.2

This might affect Apache as well. But I haven't checked, as we have not Apache running.

proposed fix

Patch attached Allow_proxy_protocol_to_use_http2_instead_of_http1_1.patch
