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
