test-connection: test connection to some target, for Felix FV testing.

Usage:
  test-connection <namespace-path> <ip-address> <port> [--source-ip=<source_ip>] [--source-port=<source>] [--protocol=<protocol>] [--duration=<seconds>] [--loop-with-file=<file>] [--sendlen=<bytes>] [--recvlen=<bytes>] [--log-pongs] [--stdin] [--timeout=<seconds>] [--sleep=<seconds>]

Options:
  --source-ip=<source_ip>  Source IP to use for the connection [default: 0.0.0.0].
  --source-port=<source>   Source port to use for the connection [default: 0].
  --protocol=<protocol>    Protocol to test tcp (default), udp (connected) udp-noconn (unconnected).
  --duration=<seconds>     Total seconds test should run. 0 means run a one off connectivity check. Non-Zero means packets loss test.[default: 0]
  --loop-with-file=<file>  Whether to send messages repeatedly, file is used for synchronization
  --log-pongs              Whether to log every response
  --debug                  Enable debug logging
  --sendlen=<bytes>        How many additional bytes to send
  --recvlen=<bytes>        Tell the other side to send this many additional bytes
  --stdin                  Read and send data from stdin
  --timeout=<seconds>      Exit after timeout if pong not received
  --sleep=<seconds>        How long to sleep before seding another ping

If connection is successful, test-connection exits successfully.

If connection is unsuccessful, test-connection panics and so exits with a failure status.
