Bug Description

When using SSL the ceilometer charm can fail to start apache. Juju status shows:

ceilometer/0 blocked executing 1.25.6 1 8777/tcp 10.5.28.171 Services not running that should be: apache2

The unit logs show:

2016-10-11 10:33:46 INFO identity-service-relation-changed * Restarting web server apache2
2016-10-11 10:33:46 INFO identity-service-relation-changed (98)Address already in use: AH00072: make_sock: could not bind to address [::]:8767
2016-10-11 10:33:46 INFO identity-service-relation-changed (98)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:8767

The problem appears to be down to apache trying to bind to port 8767 when the ceilometer service is bound to it.

Without SSL, on bare metal, I'm seeing this randomly but noticeably. Do you think it is related?

    Stop/Start ceilometer-api if Apache has changed

    If the charm enables https then apache is used to terminate ssl. As
    part of this Apache listens on the port that the ceilometer API port
    was listening on and the API service shuffles down to a lower port. If
    the services are restarted one at a time and Apache goes first then
    Apache will try and bind to the port the API service is listening on
    because the API service has not yet been restarted to pick up its
    new port.
