AWS AmazonCloudWatch documentation change
Summary
Renamed file and expanded documentation about alarm suppression. Added sections explaining when to use suppression, how suppressor alarms work, and detailed explanations of WaitPeriod/ExtensionPeriod with examples.
Security assessment
The changes add documentation about alarm suppression features that help manage operational noise during maintenance/deployments. While this improves operational security by preventing unnecessary alerts, there's no evidence of addressing a specific vulnerability.
