GetScoreHistoryAbstractResponseGetCacheValueExpiryTime Method
Returns the time that the response object is considered out of date and
should not longer be used in a cached response.
To enable cache for a API call two things needs to happen. First the concrete
APIClient needs to enabled caching response by setting .IgnoreLocalCache to false.
Second, each request object must enable it by overridding GetCacheValueExpiryTime
to a value in the future.
