[leandrodamascena]

Issue number: #1330

Changes

This change modifies the name of the key generated by the idempotency methods. In case you have 2 functions with the same name, the hash is calculated only for the first one and the other one cannot use the idempotency function.

User experience

Please share what the user experience looks like before and after this change

Before to this change, the idempotency key was just using the function name:

After this change, the idempotency key includes the module and Python qualified name (PEP 3155)

It seems the Lambda function is lacking permissions to RW to DDB.

Great job! I left some comments, but I would like to share some ideas about improving the e2e tests

[leandrodamascena]

Actually I was missing the RW Permissions for DDB, but I'll investigate why I'm running fine here even without this permission.

This is SOOOOOOOOOO awesome Leandro, fantastic job! Just left a slight note for us to think about, but maybe it's not a problem.

Should we also update the docs/upgrade.md explaining the breaking change?
