ntopng behind Squid Reverse Proxy - allow setting to set HTTP/HTTPS and port

Re: Ntopng not working behind HAProxy with SSL Offload
I want to also echo the request in the above post. Please add the ability to choose what protocol HTTP / HTTPS and what port 3000/3001 ntopng runs with.
Should be pretty straightforward to add to the config page to update ntopng.sh accordingly.
Currently, the command runs with the options:

-w 0 -W 3000

I have edited it to be:

-w 192.168.1.1:3000 -W 3001

This way I can reverse proxy to port 3000 via HTTP locally.
