It was discovered that some customers' EKS clusters did not have their IMDSv2 hop limits set correctly, causing requests for key functionality to attempt IMDSv1 fallback and failing. For now, re-enable IMDSv1 fallback by way of removing the explicit disabling of `EC2MetadataEnableFallback` until better documentation, error handling, and other work can be done to inform customers that they need to correctly set their IMDSv2 hop limits.
