Support API Gateway user-defined responses

[mweagle]

When I POST a new resource to the API, I want to return a 201 (Created) status and the URL of the created resource in an HTTP header, "Location".

I'm having problems getting Location to come back to the client.

I have tried manually setting up Location as a header in the "Method Response" config of API Gateway and then creating a mapping in the "Integration Response" mapping.

Will be addressed in 0.9.0.
