//haproxy agent-check utility
//
//Inspired by http://blog.loadbalancer.org/open-source-windows-service-for-reporting-server-load-back-to-haproxy-load-balancer-feedback-agent/
//
//Responds to telnet request with CPU Idle %.
//
//Also opens up a command channel on localhost that will accept
//management commands (i.e. Drain, Stop, Ready)
//
//Can be used with haproxy's agent-check to weight traffic based on CPU load.
//
//Note: The agent check functionality was added as of version 1.5
