Fixes issue #11:
Spring Boot exposes cache metrics via the CacheMetricsRegistrar. This class expects that the decorator is of type TransactionAwareCacheDecorator in order to unwrap the decorated cache. Since the EnhancedTransactionAwareCacheDecorator is not of that type, the underlying cache is not available, and the decorated cache type is not supported by any of the available CacheMeterBinderProvider.
Thanks to @iyerha for raising and fixing!
