for the intermediate-cdr exporter, a similar .conf is
to be generated. intermediate cdr data will be available
in tables with the "int_cdr" prefix.
the macros in get_cdr_export_fields are therefore required
to switch printed table names (ie. "cdr", "cdr_tag_data")
accordingly (ie. "int_cdr", "int_cdr_tag_data").
the existing "type" argv is used as switch param.
