Ticket 528 - RFE - get rid of instance specific scripts (part 2)
    
    Bug Description:  There was a lot of rundant code in the scripts, and
                      hardcoded paths.
    
    Fix Description:  Create new functions in DSUtil.pm(for perl scripts), and
                      create a new shared lib file for the shell scripts.  Redundant
                      code was turned into functions and placed in these files.  Also
                      replaced hardcoded paths with the proper macro values.
