[tor-commits] [stem/master] Moving test imports to the runner module

commit 76e751f9c8fd338c73752a8547cedc92a95363de

    Moving test imports to the runner module
    
    Ideally the run_tests.py module should be as simple as possible, simply parsing
    the user input and calling helper functions to run the tests. To this end I'm
    moving the code for enumerating unit and integration tests into the runner
    module.
