Refactor all python test libraries to conform to python coding guidelines
Refactor robot Test Case Suite to conform to Robot code coding guidelines

Now that I have pycharm installed in a cloned VM that I resized to allow for
development tools, I see coding issues with the original code that I had

This is mostly a cosmetic change as no fundamental changes were made
to the original code

Rebased and fixed conflicts
