Add start and end ports for streams

[aanglere]

Is your feature request related to a problem? Please describe.

As of NGINX version 1.15.10, the listen directive accepts port ranges, but NPM only allow adding a stream host listening on a single port.

I wanted to setup a stream for FTP server with passive mode. In order to support passive mode, many ports are needed and it's PITA to add all of them one by one.

Ultimately, I created a custom config under data/nginx/custom/stream.conf to workaround NPM's limitation.

Describe the solution you'd like

Add start and end listening ports when creating stream host Add start and end forwarding ports Validate input (same port, same number of ports as forwarding ports)

Describe alternatives you've considered

Currently working using custom config

data/nginx/custom/stream.conf: ` server { listen 20-21; listen [::]:20-21; listen 32500-32599; listen [::]:32500-32599;

proxy_pass <INTERNAL_SERVER_IP>:$server_port; } `

Additional context

Obviously, I could continue to use custom configs, but this feature will make lives easier. Additionally, servers added through custom configs do not show up in the dashboard.

i would greatly appreciate a extension of the configuration possibilities or at least a customs field like in the proxy page
