Description of Drivers Ticket:

Looking at the Python driver implementation of AWS auth, it appears to redact the AWS session token in error messages. I do not see this redaction mentioned in https://github.com/mongodb/specifications/blob/master/source/auth/auth.rst or https://github.com/mongodb/specifications/blob/master/source/auth/tests/mongodb-aws.rst.

If the redaction is desired, should it be described in a spec?
See DRIVERS-1189 for updated details.
