docs: Clarify metric collection methods for NTH modes by younsl · Pull Request #1084 · aws/aws-node-termination-handler
* Explained how Prometheus metric collection differs between IMDS and Queue modes. * Added a warning about serviceMonitor and podMonitor being Prometheus Operator resources. * Updated Queue mode to include two methods for metrics collection: using serviceMonitor with the Prometheus Operator or adding the aws-node-termination-handler service in `scrape_configs`. * Provided an example `scrape_configs` for Prometheus in the Helm chart. * Updated IMDS mode to mention podMonitor for metrics collection.
