Serves Prometheus HTTP Service Discovery for devices on a Tailscale Tailnet.

This is a port of @cfunkhouser's tailscalesd to Python.

This only uses the public API to enumerate devices.

The tailscalsd server is configurable through environment variables.

• TAILNET: name of the tailnet to gather devices from.
• API_KEY: Tailscale API token.

• INTERVAL: poll interval of the Tailscale API (default: every 5 seconds)
• HOST: host to serve TailscaleSD (default: 0.0.0.0)
• PORT: port to server TailscaleSD (default: 9102)
