Set paths for default instance
    
    With this patch, it will be possible to install a default instance
    simply by adding the passwords in the pkideployment.cfg.  This file
    can then be used without additional alteration to add subsystems to the
    same instance, by re-running pkispawn against the config file.
    
    The patch makes sure that cert nicknames, database and baseDN , admin users
    and client db are unique per subsystem.  An option is added to reuse the
    existing server cert generated by the first subsystem and copy the
    required data to all subsystems.
