mkcloud: rabbitmq notifications needed with ceilometer

In order to add a check to the ceilometer proposal that notifications

https://github.com/crowbar/crowbar-openstack/pull/1792 we need
to prep the proposal accordingly to enable notifications in the
rabbitmq proposal if ceilometer is being deployed
