    Bug Description: cn equality index missing by default
    Reviewed by: nhosoi (Thanks!)
    Fix Description: When creating the database instance during dse.ldif processing, we do not create the user defined indexes from the defaults for this backend.  This used to work in the old setup code because that code would always add the configuration for the indexes for the new instance.  The way it is supposed to work is that a new instance should just copy the default indexes for that backend.  This works fine when adding an instance via LDAP but not during startup.  I just added a call to have this done during startup.  I also removed some obsolete indexes from the default indexes.
