------------------------------------
[~dashengju] [~revans2]
I'd like to hear your opinion about RedisStateSetUpdater and
RedisStateSetCountQuerier.
If it cannot be replaced with other logic, how about removing these classes?
If we have to support 'expires on value', it may be better to support only
String type from Trident.

> RedisStateSetUpdater writes value into String type, but it tries to retrieve
> Set's element count from String type which will throw JedisDataException.
> {code}
> if (this.expireIntervalSec > 0) {
> jedis.setex(redisKey, expireIntervalSec, value);
> } else {
> jedis.set(redisKey, value);
> }
> Long count = jedis.scard(redisKey);
> {code}
> Btw, Redis expire only applies to key, so above implementation seems to be
> invalid.
