[Ideas] [ServiceStudio] Expose REST add the ability to change structure name

• When you consume a REST web service, you can decide to keep the original structure name, for json serialization/deserialization.
• When you expose a REST web service, you can not keep the original structure name,  for json serialization/deserialization.

There should be an option to keep original structure name,  for json serialization/deserialization of an EXPOSE REST web service structure. 

Example you might have many web services under one eSpace project and you might have two structure that you want to output as the same JSON structure name.

You might even have an existing entity named X and you want to create a structure name X, but you can't do this either. So there should be an alias feature just for EXPOSE REST.
