SCPFhostLat
This test will test the host found latency.
Host will arping a ip address, tshark will caputure the package time, then compare with the topology event timestamp.
Test will run with 1 node from start, and scale up to 7 nodes.
The event timestamp will only greb the latest one, then calculate average and standar dev.
