Override response handlers

[cflipse]

different HTTP methods are going to have different needs from their response handlers; it should be easy to select a separate response handler to use, so that the same call method doesn't have to handle both DELETE and GET responses.

@cflipse is this still needed?

@solnic I don't think this is needed, I had a similar case when developing a PoC a few years back and just handed off to another class based on the verb in my adapters request/response handlers, this also allows you to do any processing that is common to all requests before handing off to dependencies.
