AWS AWSCloudFormation documentation change

Summary

Added multiple return value properties related to DB instance status and connectivity

Security assessment

The added properties improve operational visibility but don't directly relate to security controls or address vulnerabilities. Monitoring capabilities could indirectly support security but aren't explicitly security features.
