Is there any documentation on the eck-stack example chart [cloud-on-k8s/deploy/eck-stack/examples/elasticsearch/hot-warm-cold.yaml at main · elastic/cloud-on-k8s · GitHub](https://github.com/elastic/cloud-on-k8s/blob/main/deploy/eck-stack/examples/elasticsearch/hot-warm-cold.yaml) ? In particular, what are the master, hot, warm and cold `node_roles` ? How do they work together? And what about their `count` which is their statefulset replicas?
