Taking the suggestion here to move these to a sub-object. This is future
proof in the event that we need to capture more data for ApiExplorer, and
reads better.
This also comes with a rename of the namespace
Microsoft.AspNet.Mvc.ApplicationModel to
Microsoft.AspNet.Mvc.ApplicationModels.
Also tuned up some parameter and variable names for increased
understandability.
