Enable os-net-config to support and configure NFVSwitch

These changes are to generate /etc/sysconf/network-scripts/ifcfg-* and
/etc/sysconfig/nfvswitch configuration files for nfvswitch and its interfaces.
NFVSwitch is a virtual switch implementation based on DPDK for datacenter
workloads with very high throughput needs.
