Simple ModelBinders and Simple ModelBinder Poco - 1

Covers simple scenario for each model binder.
Covers scenarios mixing a POCO model binder -> Simple Model binder.

This contains tests for
HeaderModel
ServicesModelBinder
CancellationTokenModelBinder
ByteArrayModelBinder
FormFileModelBinder

Part 2 Will contain similar tests for
FormCollectionModelBinder
BinderTypeBasedModelBinder
TypeConverterModelBinder
TypeMatchModelBinder
Any leftovers for BodyModelBinder
