Add RedisEndpoint.* attributes to CacheCluster

[jmhobbs]

Fn::GetAtt on a AWS::ElastiCache::CacheCluster can also return:

• RedisEndpoint.Address
• RedisEndpoint.Port

Example JSON

  "AWSTemplateFormatVersion": "2010-09-09",
  "Description": "Example",
  "Outputs": {
    "RedisDNS": {
      "Description": "Internal DNS name of redis.",
      "Value": { "Fn::GetAtt": [ "RedisCacheCluster", "RedisEndpoint.Address" ] }
    }
  },
  "Resources": {
    "RedisCacheCluster": {
      "Type": "AWS::ElastiCache::CacheCluster",
      "Properties": {
        "ClusterName": "example-redis",
        "AutoMinorVersionUpgrade" : true,
        "AZMode": "single-az",
        "CacheNodeType": "cache.t2.micro",
        "Engine": "redis",
        "NumCacheNodes": 1
      }
    }
  }
}

Example run with my current build;

$ cfval validate example.json
Outputs.RedisDNS.Value.Fn::GetAtt ... RedisEndpoint.Address is not an attribute of AWS::ElastiCache::CacheCluster

Fail: 1 failures, 0 warnings
$ cfval --version
