Test scrapping of rabbitmq exporter from the cluster
Currently, it's our pergamon node (static infra) which does it. But, as we do not have an alertmanager, we can't trigger alerts out of the rabbitmq metrics (among other things).

In fine, being able to design new alerts to be notified when stuck listing task issue occur.
The following mr declares the same service-monitor the swh-charts way [1]
Tested through local apply and it's working, see below:
