[storm-redis] Broken Jedis Connection should be returned as broken

While using JedisPool, any broken Jedis instances should be returned as broken.
(Thanks to Apache Commons Pool 2, we can delegate verifying instances to JedisPool itself by configuration, but performance will be decreased a bit.)

We can try-with-finally with Jedis / JedisCluster instance, but Storm should be run at least JDK 6 so we can't apply it.
