Enhance an event mechanism to notify client about a redis cluster TopologyRefresh.

[kimmking]

Expected behavior

Notice lettuce could fire an AdaptiveRefreshScheduledEvent event to subcribe it by client api when Redis Cluster TopologyRefresh. And then client codes can do something for HA/consistency functions.
So I think we can add an similar event with renewSlotCache to refresh cluster view in method redis.clients.jedis.executors.ClusterCommandExecutor#executeCommand.

Actual behavior

Add a new event mechanism.

Steps to reproduce:

NONE.

@kimmking You can customize CommandExecutor, for example:

public class YourClusterCommandExecutor implements CommandExecutor { ... }

So after getting JedisConnectionException or JedisRedirectionException, execute your custom behavior.

@yangbodong22011 thanks for your idea and kind.
This is a way to fix the problem in my case, but some duplicated codes with ClusterCommandExcutor.
