pub const IAM_ROLE_ARN_PATTERN: &str = r"^arn:aws[a-zA-Z-]*:iam::\d{12}:role/.+$";Expand description
Regex for the AWS::IAM::Role.Arn schema format check: the partition must be
aws-prefixed and the role name is unrestricted (.+), so a role name containing a space or
other legal-but-unusual character is accepted here.
