proxying a service through tailscale

1. Start up a service serving traffic locally on a port - I started up elk on port 5314
2. Install tailscale on the server
   1. including sign into the tailnet
3. proxy via caddy

elk.example.com {
	handle {
		reverse_proxy <local_host_name>:5314
	}
}

and that's it! super easy, very impressive
