A sequence action for stateful requests (HTTP sessions)

Feature proposal

Since middlewares are internally used and not exposed to developers, there is no possible way to implement stateful requests, as it was done with the express-session middleware before v4.

Current Behavior

The v4 complying solution would be a sequence action, but it doesn't exist yet in RestBindings.SequenceActions.

Expected Behavior

Have a sequence action that retrieves cookies information and make it available to the app via context and dependency injection

まず RestBindings.SequenceActions と既存の sequence action の実装を読んで、コンテキストと依存性注入を通じてリクエストデータがどのように公開されるかを理解します。次に、現在の middleware と request context の処理を追跡し、その後、cookie 情報をアプリケーションから利用できるようにする sequence action を定義してテストします。
