Make ActionDescriptor accessible in IModelBinder.BindModelAsync

[djanosik]

I've found it would be useful if we could access ActionDescriptor in the IModelBinder.BindModelAsync method. In Web API 2 there is another parameter of type HttpActionContext. Can you bring it back to MVC 6?

What are you trying to accomplish? There's probably a better way to do it now with ResourceFilters

I want to decide how to bind the model according to a return type of the action method.

context.OperationBindingContext.ActionContext.ActionDescriptor - we hope to simplify it more than this, but it's possible for now.
