vpp: Reporting update related to VPP

VSPERF reports were updated to contain vSwitch name.
In case of VPP, it is not possible to read its version
if VPP is not running. Thus VSPERF was enhanced
to support tool version check during its runtime. This
mechanism can be enhanced to support e.g. VNF in the future.

JIRA: VSPERF-496
