DDL Sequencer support for Teiid creating global temporary tables

Add in support for the following Teiid DDL statement:

CREATE GLOBAL TEMPORARY TABLE myTemp ("
                            TAB + "x string,"
                            TAB + "y SERIAL,"
                            TAB + "PRIMARY KEY(x)"
                            ")";

The Teiid DDL Sequencer component needs to support:

• CREATE GLOBAL TEMPORARY TABLE syntax
• Understand the SERIAL pseudo data type, which substitutes for a non-null auto-incrementing integer.
