In order to support output properties (pulumi/coconut#90), we need to modify the Create gRPC interface for resource providers slightly. In addition to returning the ID, we need to also return any properties computed by the AWS provider itself. For instance, this includes ARNs and IDs of various kinds. This change simply propagates the resources but we don't actually support reading the outputs just yet.
