…hat return strings which are assumed to conform to be the proper string representation of a stricter type, such as a CIDR block.
The motivation for this change is that using Fn::GetAtt to get the results of a custom resource is essentially a Token[String], which cannot be used with more specific type requirements, such as a Token[CidrBlock] needed for a VPC or Subnet.
This change allows for a custom resource to output a value as a string, which can be retrieved with a Fn::GetAtt, wrapped in UNSAFEFunctionCallToken, and used as a parameter for a another resource. This change is backwards compatable and will not break any existing cftg code.
