Filter internal constructs from oracle metadata

Even with the import table types set to TABLE, an Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 accessed with the 12.1.0.1.0 driver will contain internal tables which will cause the deployment to error:

TEIID31071 Invalid table; Table oracleModel.HS_PARTITION_COL_NAME has no columns defined

It would be good if these were filtered by default. The workaround is to specify a schema or regex to prevent such tables from being imported.
