Title: [rackspace] remove deprecated response block from request

Passing a response block to `Excon::Connection#request` was deprecated in favor of passing `:response_block`.
This was only being used with `Storage::Rackspace#get_object`, which was setting `:response_block` _and_ passing that block to the request.
