Follow up to #50550. Cache empty nodes lists (
fetchDynamicNodeswill return an empty list in case of failure) now that the plugin properly retries requests to AWS EC2 APIs.Note: I'd suggest adding tests for the exception handling once #50605 is in and we can add them cleanly by using a mocked REST APi instead of adding more actual mocking of AWS SDK classes for this.
