[kddejong]

Is this feature request related to a new rule or cfn-lint capabilities?

rules

Describe the feature you'd like to request

As we convert to the schema there is new properties. We can look at primaryIdentifier (minus readOnlyProperties) and validate those primaryIdentifiers are unique against all resources in a template.

Example of this would be RoleName in AWS::IAM::Role

Describe the solution you'd like

A new rule that validates the uniqueness of primaryIdentifiers across all resources of a type
