Adding the unit tests for the clean_workspace tool
Created by: prwolfe
As we discussed getting these to always run is vital. I will be working on python 2/3 coexistence next.
Just adding the make spec to get these python tests running.
Motivation and Context
All testing should happen at PR time as well as by hand.
How Has This Been Tested?
Built as if in a PR test and ran the python tests by hand.
