When we restart HAproxy, we kill all the connections and it causes all of the services to be dropped out. This is really not ideal and causes things to be lost in the control plane. This patch instead does a reload which will safely keep the existing clients connected till they evacuate and then use SO_REUSEPORT for the new process.
