AWS fis documentation change
Summary
Added documentation for new EBS volume I/O latency injection actions in AWS Fault Injection Simulator
Security assessment
Documents new fault injection capabilities for testing resilience. While these actions could impact system availability, the documentation update itself does not address a security vulnerability or describe security features.
