CSIT-524: Traffic generator using python profiles
Profile name structure:
[trex|ixia]-[sl|sf]-[topo]-[packet structure]-[scale]
- Traffic generator - T-rex (trex) or Ixia (ixia)
- Stateless (sl) or statefull (sf)
- Topology - 2-node topology (2n) or 3-node topology (3n)
- Packet structure - eth | ip4/6 | udp
- Scale - e.g. ip4dst1, ip6dst10000, 4000u15p
