Note: This module sets up AWS IAM Roles and Policies, which are globally namespaced. If you plan to have multiple instances of AWS Config, make sure they have unique values for config_name.
Note: If you use this module in multiple regions, be sure to disable duplicate checks and global resource types.

Version 2.4.0 changed how AWS Config IAM polices would be attached to IAM roles. When applying the upgrade, you will likely see a race condition resulting in the following error
Error: Provider produced inconsistent result after apply
A second terraform apply should resolve the issue.
