Attach a callback to a hook. Three hooks are currently implemented:

            before_request
                Executed once before each request. The request context is
                available, but no routing has happened yet.
            after_request
                Executed once after each request regardless of its outcome.
            app_reset
                Called whenever :meth:`Bottle.reset` is called.
