[storm-redis] Provide binary version of TupleMapper and corresponding mappers

For now storm-redis only provides string version of mappers which makes issues with binary key, field, and value. While converting data, data can be messed, or at least there should be time / space consuming.

Redis originally takes binary data, and also Jedis has binary methods set. It should be better that storm-redis supports binary data, and after this state is not needed to be converted with base64.
