Description

The Python client does not currently support transaction savepoints, but they are an essential feature. For example it's currently impossible to recover from errors (e.g. `CardinalityViolationError`) within transactions - the entire transaction has to be retried. There are additional difficulties arising in test writing and when dealing with external failures without losing (all) progress in a transaction.
