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.
