Support python v3.10 - Githubissues

Related issue https://linear.app/serverless/issue/SC-900/support-aws-lambda-python-v310-runtime
I've tried to run the unit tests with python3.10 and found a single piece of code that needed a change because they've changed the signature of traceback.format_exception (first argument is ignored since python 3.5+)

Unit and integration tested against python 3.10
