Use a certbot pre-hook to ensure haproxy backend is up before renewal

openstack/openstack-ansible-haproxy_server

Code Issues Proposed changes

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.
