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

Start by reading RestBindings.SequenceActions and the existing sequence-action implementations to understand how request data is exposed through context and dependency injection. Trace the current middleware and request-context handling, then define and test a sequence action that makes cookie information available to applications.
