vnfs: configurable loopback application support inside VM
For PVP and PVVP deployments, traffic inside virtual machines must be forwarded between its interfaces. There are several forwarding options supported by VSPERF, including DPDK testpmd, Huawei l2fwd kernel module and linux bridge. Another option is, that VM image has built in forwarding functionality and vsperf doesn't configure it itself. User can select VM loopback application by configuration option GUEST_LOOPBACK (per VM) or by SCALAR cli option guest_loopback (global settings). Selected guest loopback application(s) will be written into test results CSV file and test report MD file. Default wildcarded guest login prompt was added. Guest startup guarding timer can be configured. Path to OVS kernel module has been fixed.
