title: access `IValueProvider` or `ModelBinder` in ActionFilter/IResultFilter
body: <p>I'm creating a <code>IResultFilter</code> that automatic detect some query parameters and write paging info to the header and also process the result (if result is <code>PagedResponse&lt;T&gt;</code> or a <code>ObjectResult.Value</code> is <code>IEnumerable&lt;T&gt;</code> then I will paging the result and also add paging info to the header  and all that happen in <code>PagedObjectResult</code>)</p>
  
  <p>current I manually bind my <code>PageRequestParameter</code> with <code>context.HttpContext.Request.Query["PageSize"]</code>, but is there a way to use <code>IValueProvider</code> or <code>Modelbinder</code> to get my <code>PageRequestParameter</code> object ?</p>
