A simple SSNTP server that can be used to perform unit testing of the CNCI
agent. The CNCI Test Server sends a stream of event and command to any CNCI

has to be run a machine that is different from the one that is hosting the
CNCI VM.
This is required as the CNCI VM uses macvatap for networking and macvtap
traffic cannot be received by the host whichout complex network plumbing
