APIGW: internalize DeleteIntegrationResponse

[bentsku]

Motivation

While looking at the some exception reports, I've spotted the following:

exception while calling apigateway.DeleteIntegrationResponse: 'NoneType' object has no attribute 'to_json'

Looking at the code, it seemed there was almost no validation, and the code would do a value.get(x, None).to_json() which would fail.

We can internalize the DeleteIntegrationResponse and add a bit of validation

Changes

• add test around validation of DeleteIntegrationResponse
• implement DeleteIntegrationResponse in our provider
• moved code around to group handler that are about the same resource
