UDP socket does not close once parent process is killed

as discovered by https://github.com/swissmanu/orchestra/issues/2, the udp socket used for the discover broadcasts is not closed properly once the parent process gets killed.

Problem here is the UDP socket opened in https://github.com/swissmanu/harmonyhubjs-discover/blob/ba774fd1046e920d1e366e240e67d06f031df57e/lib/ping.js#L8 that is never fully closed.

Doing discover.ping.socket.unref(); after stop seems to fix the issue for me.
