Proxy Preserve Host option on Custom Locations and Proxy Hosts

[mcarbonneaux]

By default nginx seem to don't preserve the host port (in certain case).

in some case is usefull like in esphome/issues#4327 to preserve the host AND the port.
in apache you have an options to do that ProxyPreserveHost, in nginx you can use http_host variable to that.

in this maner:

proxy_set_header Host $http_host;

it would be possible to add an option (in proxy host and in custom locations) to pass the host as is (with port) in the Nginx Proxy Manager as flag on/off to simplify the usage ?
