Summary
This PR makes the list of EC2 scaling error codes configurable instead of hardcoded in the control-plane Lambda. It allows users to extend or override the default retryable error set without forcing a change on everyone.
Motivation
Issue [#4105] was closed without a PR, leaving the scale error list hardcoded.
Different environments can encounter additional EC2 error codes that should trigger retries; making this list configurable lets users adapt behavior without modifying the library code.
