Optimizing HAProxy CPU usage for SSL

Hi, We recently hit an issue where we observed the haproxy_frontend_current_sessions reported by the prometheus endpoint plateau at 4095 and some requests start dropping. Increasing the global and listen maxconn from 4096 to something larger (as well as making the kernel TCP queues on our Ubuntu
