testpmd_pvp: Adds pkt_fwd to allow pvp topology testing

Requires DPDK 16.11 or greater to support vdev flags.

Initial support for TestPMD to support guests.

Allows vsperf to execute TestPMD as a switch for pvp
test scenarios.

Can be increased in functionality later to support
multiple guest configs.

JIRA: VSPERF-406
