[Suggestion] HTTP Basic password auth need extra port for nginx

[yevdev]

While i'm not sure what monster would port scan, and find the feeder service if it is publicly accessible and dispense all food! However, I figured adding nginx passwords using a .htpasswd was sufficient enough.

I solved this ultimately by allowing a 3rd port, 8443 that is an exact copy of the :443 server binding, with just a small edit of

location / {
auth_basic "Dragons Ahead";
auth_basic_user_file /data/.htpasswd;

Small notes

• Looks like the feeder uses the API :443 for health checks? Adding a password directive here seems to cause the feeder to stop phoning home and become unresponsive.
• I run petnet on my local network, however, I use DynamicDNS and port forwarding (custom port -> 8443 exposed to the world) to allow access from my mobile phone. I have two cats, and a Nest cam to monitor the bowl and I like the ability to just manually feed based on how much is visible.

The system runs great on Ubuntu 18.04 on a small VM, and Raspberrypi pi-hole to intercept DNS and reroute to the VM.
