aiohttp: fix multiple requests being replayed per request and add support for request_info on mocked responses (#495)

* Fix how redirects are handled so we can have requests with the same URL be used distinctly

* Add support for request_info. Remove `past` kwarg.

* Remove as e to make linter happy

* Add unreleased 3.0.0 to changelog.
