A very simple UDP logging server, for the purposes of demoing and testing running a UDP based server on Agones.
Starts a server on port 7654 by default. Can be overwritten by PORT env var or port flag.
When it receives a text packet, it will send back "ACK:" as an echo.
If it receives the text "EXIT", then it will sys.Exit(0)
