Ticket 48333 - Simplify accessiblitiy of tests for ds
    
    Bug Description:  Previously, it was hard to run the full test suite without
    scripting or other external means. We want to be able to run
    
    py.test dirsrvtests
    
    To test the full scope of the application. We can also use this to trigger
    specific tests:
    
    py.test dirsrvtests -k test_ticket48109_1
    
    Fix Description:  To achieve this, we create __init__.py in all the needed
    folders, to make the python path accessible by py.test to discover all the
    tests. Additionally, we add __pycache__ and *.pyc to gitignore
