ListResource from https://aws.amazon.com/blogs/aws/announcing-aws-cloud-control-api/ could increase coverage quicker

@PatMyron - I had looked at that when it was announced, but at the time it actually supported less resources than awsets. It might be better now, but still doesn't solve the relationship aspect, which was one of the primary goals. I'd love for AWS to do this better though!
