AWS prometheus documentation change
Summary
Added new metrics for out-of-order sample ingestion and corresponding error reasons, including documentation for percentile dimensions.
Security assessment
The changes add operational metrics for monitoring data ingestion anomalies. While helpful for reliability, they don't address security vulnerabilities or introduce security features. The 'out-of-order-rate-limit' error relates to service quotas, not security controls.
