Tool for check connection between secondary network interfaces

This tool will check connections regarding CIDR resource list.

It will create Iperf3 server pod for all related hosts and then sequentially run Iperf3 client job for each interfaces on each pod.

Run locally:

make local-run

Clean up:

make clean

Expected output (for n server):

... 
<timestamp> <n>/<n> servers successfully created
...
