Construct library pattern for resources that need IAM roles

[eladb]

• Implement and apply rule awslint:role-config-prop: If the CloudFormation resource has a "Role" property the construct must have an optional "role: IRole" prop
• Implement and apply rule awslint:role-property: Constructs with a role should have a "readonly role: IRole" property on their construct interface
• Implement and apply rule awslint:role-add-to-policy: Constructs with a role must have an "addToRolePolicy" method on the construct interface
• Implement and apply rule awslint:resource-policy-prop: The "resourcePolicy" prop should be optional and accept an array of PolicyStatements
• Implement and apply rule awslint:resource-policy-add-to-policy: Constructs that have a resource policy should have an addToResourcePolicy method on their interface
