settings: document the possibility of using Unix sockets

We have been supporting Unix sockets by ages, because express.listen()
(http://expressjs.com/en/4x/api.html#app.listen_path_callback) re-exposes
net.server.listen() (https://nodejs.org/api/net.html#net_server_listen), which
in turn supports Unix sockets.

The only remaining thing to do was documenting it.

Fixes #3312
