AWS rtb-fabric documentation change

Added warning about ensuring ASG hosts marked IN_USE are healthy and available
Security assessment
The change emphasizes operational reliability by ensuring traffic routing to healthy hosts, but there is no evidence of addressing a security vulnerability or describing security-specific capabilities. This is a reliability/availability concern rather than a security fix.
