Breaking Changes

• the CacheMap signature has been changed to correctly reflect that it is a cache of CompletableFuture<V> and not just <V>

Other changes

• a new ValueCache layer has been added to that allows values to be stored in external cache systems such as REDIS or long lived cross request systems like Caffeine

• A new last dispatched time is present on DataLoaders

• An experimental ScheduledDataLoaderRegistry that allows new ways to dispatch dataloaders.
