sriov: Support of SRIOV and Qemu PCI passthrough

Generic support of SRIOV has been added. Virtual interfaces can be
used in multiplei scenarios instead of physical NICs. Virtual
functions can be directly accessed from VM by PCI passthrough method.
Another option is to use VFs with vSwtich to evaluate impact
on performance.
Additonal modifications:
* Automatic detection of NIC details has been added to simplify
configuration.
* Obsoleted configuration options have been removed.
* Logging usage within vsperf script was fixed.
* Vsperf main was refactored and final cleanup function added.
* Configurable forwarding mode of TestPMD executed inside VM.
