add Identity() for remaining examples

Fixed the performance example scripts in examples/performance to mostly
work with the Oracle database, by adding the :class:`.Identity` construct
to all the tables and allowing primary generation to occur on this backend.
A few of the "raw DBAPI" cases still are not compatible with Oracle.
