Add package: tailscale-rm-webint

[rM-self-serve]

This program is a reverse proxy that will enable interaction with the USB web interface over Tailscale.

Tailscale needs a service to run on localhost in order to share it with the network. This program will open a port on localhost and forward requests to the USB web interface at 10.11.99.1:80.

In order to test the package, tailscale is not required. Simply verifying that the USB web interface is accessible at 10.11.99.1:80 and 127.0.0.1:80 will be sufficient.

I am the author.

Question before merging, should this package depend on tailscale? It does not require tailscale to run but does not have any purpose unless tailscale is being used.

It might be worth just renaming this to not be tailscale specific since this just is a proxy to expose something on localhost.

All that said, it would probably be better to use socat or systemd-socket-proxyd (if it's available) to handle proxyong things here instead of having a custom built executable. This way we only need to handle being the glue to configure it instead ofqking sure a custom binary continue to build and work on the device.

I have a working solution using systemd-socket-proxyd.

Two questions:

1. Is there any way to let a user change the port of the systemd socket? I believe the socket should listen on port 80 by default but a user may want to change this behavior. Right now I have ListenStream=127.0.0.1:80 in the .socket file.
2. Would the name 'webinterface-localhost' be a more apt name?

Users can override the .socket file to change the port.

Probably
