Add the CacheNodeInfo related columns to the aws_elasticache_cluster.

[dongho-jung]

Is your feature request related to a problem? Please describe.
While identifying DB assets and organizing the endpoints of the instances, it is difficult to achieve this with the current columns of the aws_elasticache_cluster table.

Describe the solution you'd like
If ShowCacheNodeInfo is passed as a parameter when calling DescribeCacheClusters, I can get additional information about individual cache nodes. Therefore, I intend to utilize this.

Describe alternatives you've considered
For now, I plan to temporarily use the exec plugin and AWS CLI, but it seems more natural for the aws_elasticache_cluster to support this natively.

Additional context

• Simply passing ShowCacheNodeInfo in every query raises concerns about performance degradation. Therefore, I want to pass this parameter only when columns like cache_node_endpoint or cache_node_status are included in the select statement. I'm curious if there are any best practices for this approach.
• By appending ShowCacheNodeInfo, we can obtain the following information. Please refer to the image below.
  
  • I only need the endpoint information here, but other information could be useful elsewhere.
