DataPump Export doesn't extract the 'parallel' clause in the dump file for global temporary tables.

Example:
-----------
- On source database,  a global temporary table is created with the following parallel clause:

create global temporary table "SCOTT"."TMP_JOIN_PORTION_20" (satz number) parallel 4;

- DBA_TABLES view shows the degree level set to 4 for this table:

SQL> select table_name, degree from dba_tables where table_name='TMP_JOIN_PORTION_20';

TABLE_NAME                                                             DEGREE
--------------------------------------------------------------------------------
TMP_JOIN_PORTION_20                                             4

- Datapump Export and subsequent Import create the table on the target without the parallel degree.

- Checking the dump file created by the export and generating the sql file for that table on the source database shows:

CREATE GLOBAL TEMPORARY TABLE "SCOTT"."TMP_JOIN_PORTION_20"
  ( "SATZ" NUMBER
  ) ON COMMIT DELETE ROWS ;

=> the DDL statement doesn't have the parallel degree option it had when it was initially created.
