Description
Allows modifications to the assume role policy of the flow log IAM role.
Motivation and Context
The recommended action by AWS to prevent confused deputy attacks is to add sourceArn, sourceAccount or sourceOrg as conditions as condition to the role assumption. https://docs.aws.amazon.com/IAM/latest/UserGuide/confused-deputy.html
Breaking Changes
Should not break anything, as the default variable is empty and will simply not render the dynamic block.
