ScopedProvider is now more similar to standard Guice's Provider By hiding the HttpServletRequest inside the HttpSessionProvider, the ScopedProvider<T> can be now 100% compatible with the standard Guice's Provider<T> interface. Moving as well from constructor injection to field injection so that the concrete implementation do not have to replicate the constructor injection definition. Code is more compact and extensible. The ability to get an instance by passing an actual HttpServletRequest is kept in order to allow the standard servlet filter (outside the Guice domain) to retrieve the object in the current session, without having to request a Provider<HttpServletRequest> which would fail.
