samples: Add generic L3 forwarder tests

A generic throughput test case that can be used as a
stub code for a Linux-based VNF configured as an L3 forwarder.

Supported context:
* Standalone OVSDPDK and SRIOV
* Baremetal

Code changes:
* Allow pmd-cpu-mask and lcore mask for OVS DPDK
* router_vnf.py - configures interface IP addresses and static arp entries
  using ip command
* NFVi KPIs
* Allow cputune tag for standalone context to be able to PIN on NUMA 1 cpus

SRIOV Test cases:
* RFC2544 Ethernet framesizes, 128K Flows
* 2,4 and 6 ports
* 2 and 3 vcpus per port
*
OVSDPDK Test cases:
* RFC2544 Ethernet framesizes, 128K Flows
* 2 and 4 ports
* 2 vcpus per port
* 2 PMD threads per port

TODO:
* Documentation
* Add 6 ports tests

References:
* router_vnf.py is based on sample_vnf.py
* tc_*.yaml files are based on acl/vfw test case files

Added unitests
Added get_stats to parse ip -s link
