Remove twophase for cx_Oracle 6.x
Support for two-phase transactions has been removed entirely for cx_Oracle when version 6.0b1 or later of the DBAPI is in use. The two- phase feature historically has never been usable under cx_Oracle 5.x in any case, and cx_Oracle 6.x has removed the connection-level "twophase" flag upon which this feature relied.
