DATAREDIS-503 - Add HashMapper implementation based on MappingRedisConverter.

We now support mapping of simple and complex types to Redis HASH structures applying the same structure as the Repository support. This allows Object to hash Mapping and its direct usage via RedisTemplate without the need of explicitly having to use the repository abstraction.

Original pull request: #194.
