//TODO:
- make_response analog to make_error_response (could be good extension point to support JSON, 302 Redirect replies or custom peculiar types)
- Make request.CONTEXT.getUserID() (it will eliminate dependence on UserAuthN)
- Make interface for storage policies
- URI as class
- Review URI parsing against RFC3986 #3
- Remove logic from storage (if any)
- Make language resource loader Interface

//HACK:
- RS not check token type in TokenValidator
- RS only check grant in TokenValidator
