Issue 49717 - Add conftest.py for tests
    
    Bug Description:
    From the test's output it's not possible to tell what version of
    389-ds-base was used during the test, what are the versions of
    libraries that we depend on, etc.
    
    Fix Description:
    We can use conftest.py to print this useful information. This also will
    be reflected in an html report, if py.test is used with --html option.
