Add new testcase for LTD.Scalability.RFC2544.0PacketLoss

This test adds a multistream config item,
taking the required number of flows to setup in the traffic,
to the existing testcase and then running the standard
2544 Throughput test. The config is plumbed through
from the 01_testcase.conf via ITraffic to the IxNet.
01_testcase.conf contains new parameter MultiStream
for 2544 Throughput test.
