Adding `response` and `cookies` methods from Rails to the Strategy environment.
Adding `response` and `cookies` methods from Rails to the Strategy environment.

This are needed for storing cookies to the Rails environment, if we try to add cookies
via the normal Rack::Response class, then Rails is going to ignore them completely this
is because there would be 2 different Response instances (The one from the Strategy,
and the one from Rails).
