makeRequest function receives a body even for GET requests (and DELETE as well)

[mutedchaos]

The makeRequest method is passed an empty object as a body even when the API is a method that does not support one, which potentially unnecessary complication to the implementing logic as libraries might reject a GET request with a body, and evidently AWS API gateway does as well.

This should be pretty safe to change for GET requests, DELETE is more problematic as although it is not supposed to have a body, it is not entirely unusual for people to intentionally make DELETE requests with a body. Maybe there should be some compatibility options for this...?

At the very least the existing behaviour should be documented.
