SimpleDnsServer random port range has been fixed

`bitnami/redis-sentinel` and `bitnami/redis` versions have been fixed as well.

The test is always failing

Below is the error: ``` org.awaitility.core.ConditionTimeoutException: Condition with Lambda expression in org.redisson.RedissonTopicPatternTest was not fulfilled within 1 minutes. at org.awaitility.core.ConditionAwaiter.await(ConditionAwaiter.java:167) at org.awaitility.core.CallableCondition.await(CallableCondition.java:78) at org.awaitility.core.CallableCondition.await(CallableCondition.java:26) at org.awaitility.core.ConditionFactory.until(ConditionFactory.java:1160) at org.awaitility.core.ConditionFactory.until(ConditionFactory.java:1129) at org.redisson.RedissonTopicPatternTest.lambda$testResubscribeInSentinel$20(RedissonTopicPatternTest.java:483)...

Same test but for the cluster mode. Doesn't reproduce the issue. Can you adopt your test to the cluster mode? ```java @Test public void testReattachInCluster2() { SubscriptionMode subscriptionMode = SubscriptionMode.MASTER;...

Is there any code to reproduce it? Which application server is used?

Are there any other exceptions in the logs? NPEs or something?

@huangshaobb Thanks for the dump. Does it hang on RedissonClusterConnection.del() method only? >yestoday night the redis cluser restart Does it happen after cluster restart?

Is there any code example to reproduce that?

@seakider check if `CommandAsyncService#evalAsync(NodeSource nodeSource, boolean readOnlyMode, Codec codec, RedisCommand evalCommandType, String , List keys, boolean noRetry, Object... params)` and any other nested methods correctly release `params` and `keys` objects.
