Allow custom limiter when Dingo\Api\Contract\Http\RateLimit\Throttle also implements HasRateLimiter.

This would allow custom Throttle to define the rate limiter key resolver within the class (instead of declaring it globally). This would allow different Throttle to use different rate limiter key values.
