Set Redisson config using AWS ElastiCache as Clustered Mode

See original GitHub issue

Hey there!

What is the proper way to configure Redisson when you have a AWS ElastiCache Redis running as Clustered Mode? I have tried to set using it as follows:

    val nodeAddress = "redis://test-rest-encryption-0001-001.p0vefj.0001.use1.cache.amazonaws.com:6379" 
    val config = Config()
    val configCluster = config.useClusterServers().addNodeAddress(nodeAddress)
    val client = Redisson.create(config)

Node endpoint: test-rest-encryption-0001-001.p0vefj.0001.use1.cache.amazonaws.com Configuration endpoint: test-rest-encryption.p0vefj.clustercfg.use1.cache.amazonaws.com

For nodeAddress, I have tried to use configuration endpoint and node endpoint but fails in both case (connection timed out):

21:04:39.542 [main] WARN  o.r.cluster.ClusterConnectionManager - connection timed out: test-rest-encryption-0001-001.p0vefj.0001.use1.cache.amazonaws.com/172.31.19.41:6379

Am I missing something?
