Add fast execution helper support.
Added a new flag ``use_batch_mode`` to the psycopg2 dialect. This flag
enables the use of psycopg2's ``psycopg2.extras.execute_batch``
extension when the :class:`.Engine` calls upon ``cursor.executemany()``.
This extension provides a critical performance increase by over an order of magnitude
when running INSERT statements in batch. The flag is False by default
as it is considered to be experimental for now.
