Action results pattern

[yishaigalatzer]

Examples:

JsonResult allow status code on JsonResult.

RedirectResult exposes the url but doesn't let you change it.

Also redirectresult eagerly resolves UrlHelper just to find out if a Url is local (which means a service is resolved on every call unnecessarily).

See:
https://github.com/aspnet/Mvc/blob/dev/src/Microsoft.AspNet.Mvc.Core/ActionResults/RedirectResult.cs#L35

Suggested pattern: Every result exposes properties as get set, so results filters can modify them and observe the values.

Services are resolved on a per needed basis, and not eagerly.

Static things like IsLocalUrl are not done as Transient services, they can either be static methods or Singleton services.

Needs discussion and break down.
