Ticket 47999 - lib389 individual tests not running correctly
     when run as a whole
    
    Description:  Each test should delete the instances it creates.  That way each new test
                  truly starts fresh.  Otherwise if running all the tests, like in jenkins,
                  or running py.test, there are no conflicts and unexpected instances in
                  the mix.
    
                  Made sure all the tests call the "final" function, and that the "final"
                  function deletes any instances it creates.
    
                  Also fixed the formatting of all the scripts to be compliant with python
                  coding standards.  Removed lines that accidentally ended with ";", and
                  fixed deprecated processes.
