[NSB] Adds support for running "black box" test cases for VNFs

Using AgnosticVNF is now possible to create a "black box"
testcase for any VNF.

Example rfc2544 test with TRex as trafficgen

samples/vnf_samples/nsut/agnostic/tc_baremetal_rfc2544_ipv4_64B_trex.yaml

and Ixia

samples/vnf_samples/nsut/agnostic/tc_baremetal_rfc2544_latency_ipv4_64B_ixia.yaml

NOTE:
    Yardstick will not interact with VNF.
    No KPIs from VNF will be collected

JIRA: YARDSTICK-1438
