Add FEATURE_QUALIFIED_TABLE_NAMES capability

When creating a connection to an Oracle database, DBUnit will populate a
Map of table names. By default these will not be prefixed with the
schema name. As a result, you can get duplicate table names or you
cannot use schemas using this plugin.

I am using an Oracle Database with diferent Schemas.
