Implements Closeable to Pooled Jedis & ShardedJedis

* Implement Closeable from Jedis, ShardedJedis with Pooled
** resources from JedisPool, JedisSentinelPool, ShardedJedis, ShardedJedisPool
* Connection class : check whether Jedis Connection is broken
** when it's time to throw JedisConnectionException, mark Connection to broken
