This fixes the exception of
botocore.exceptions.ClientError: An error occurred (ValidationException) when calling the PutParameter operation: Invalid request: tags and overwrite can't be used together.

This will make the IAM user and API keys durable across API
stack rebuilds.
This also grants the IAM user rights to invoke all deployments
of the API and all SQS queues used by the API
Deal with exceptions differently depending on if the function was called
