If a unit is paused then its services will not start during the
post-series-upgrade hook. In addition exclude haproxy from the list
of services to start if it is being managed by hacluster.
Currently, Apache ports.conf file is not being configured by this
charm. This patch changes the ports.conf default file with another one
that does not open port 80 on SSL environments.
When resuming services exclude those managed by hacluster, in
this case haproxy. If pacemaker lacks quorum it may shut haproxy
down which will cause this charm to error.
Charmhelper sync included to bring in required
get_managed_services_and_ports method.
