The request/response interception has not yet been used, and introduced quite a bit of complexity, especially surrounding fetchMock. Furthermore, they made our DSVM tests fail, as the browser's implementation of Request requires that a request body be accessed using the regular json(), text(), etc. promise generators. Since this would have simply added more complexity to an already complex, unused feature, we've simply removed the feature. Change-Id: I4cdf7b7106c771f0562de47e8835076d48d03a31
