CSIT-465: Common test setup and teardown
This test setup and teardown is aimed to be used with all functional tests. It does not include functionality to manipulate VMs (qemu). Test setup includes: - Setup all DUTs before test - Save VPP PIDs - Setup all TGs before traffic script - Update All Interface Data On All Nodes Test teardown includes: - Show Packet Trace on All DUTs - Show vpp trace dump on all DUTs - Vpp Show Errors On All DUTs - Check VPP PID in Teardown Change-Id: Ifee0bd58b7865442c5b510852908fd8363e3c543 Signed-off-by: Tibor Frank <tifrank@cisco.com>
