We use the built in python3 http server to bring up a temporary backend on the node which wants to renew a certificate. The timeout set so that the haproxy health check has noticed the backend come up before certbot runs. There is otherwise a race condition between the haproxy healthcheck and the certbot challenge request arriving at the acme-challenge endpoint. Change-Id: I2f5f9457c43c68f2881bf9d44f43434ca7b43859
