Adding feature to configure upload size with annotation

Because there are some times we want to configure upload size with different values for another method. Or we want to configure a value without overriding a class.

If you like it, I'll add documentation.
It's not that ok to break compatibility between 4.1.0.RCX and 4.1.0.Final

we can use `controllerMethod.getMethod().getAnnotation()` meanwhile.
