framework: Add reworked framework to repo
This commit adds the vSwitch Integration Test Framework whose design, based off TOIT, is outlined in the HLD previously made availiable to the community for review. The design of this framework allows developers to add different implementations of components, specifically vSwitches, Traffic Generators, Metrics Collectors and VNFs, easily. The goal of this design is that all testcases should run regardless of what is "under the hood". This commit adds support for running the framework for a phy to phy RFC2544 testcase only. More testcases will be added by the community. vSwitches supported at this time: * Intel DPDK (r) accelerated OpenvSwitch Traffic Generators supported at this time: * IxNet - IxNetwork Implementation * Ixia - IxExplorer Implementation * Dummy - Manual Implementation Metrics Collectors supported at this time: * Linux Metrics No VNFs are supported at this time but the framework outlines how they should be integrated and provides APIs for them to adhere to.
