Set to interface{} instead of *interface{}

Start with the supplied Swagger declaration and the Java generation command using swagger-codegen 2.3.1, then inspect the Go generation path that maps an object property to a Go type. Reproduce the generated *interface{} with the linked RingCentral example and verify the output is interface{} while preserving valid handling for structs and pointers.
