VOL-2642 Add a Makefile, tests, and virtualenv

Convert common python and robot into a CORDRobot python module that can
be installed via standard python tools (pip) and from PyPI

Uses a fork of https://github.com/rasjani/robotframework-importresource,
which has been backported to Python 3.5 (used in Ubuntu 16.04
executors).

Reformatted and moved keywords so resource files are scoped to a
specific topic.

Added tox tests for library consistency

- flake8
- pylint
- robotframework-lint
- Ran robot against installed library to verify it can be loaded and
  used

Added basic lint and tests to whole repo

Removed old tests:

- CORD <6.x era: SanityPhyPOD.robot, and onosUtils.py
