714577c83e PYTHON-1508 commitTransaction can be called multiple times 
This change allows applications to check if their transaction was commited or
not by repeatedly calling commit until the transaction state is known.
If a session is used after a commit for any operation (not including
another commit), the operation is not part of a transaction and the session's
transaction state is reset.
