Interface HintOptionChecker

Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface public interface HintOptionChecker
A HintOptionChecker validates the options of a RelHint.

Every hint would have a validation when converting to a RelHint, the validation logic is: i) checks whether the hint was already registered; ii) use the registered HintOptionChecker to check the hint options.

In HintStrategyTable the option checker is used for hints registration as an optional parameter.
