Resolve data from Resource Facade

Since we are looking directly at the template data for the resource facade,
we need to resolve any intrinsic functions that may be present. (For
example, this would be expected if we ever had more than one level of
provider templates, or if e.g. the DeletionPolicy was passed as parameter
to the main stack).
