{{/*
The following Service resource will be created upon certain conditions:
- The ServiceMonitor integration is enabled
- A Service resource must be created

The reason for that is that the Ingress Controller would make it available to the outside
sensitive data such as its metrics, and the operator wants to keep these data private
(such as the value of "controller.service.enablePorts.stat=false").

To let the Prometheus Operator being able to scrape the metrics, an additional service
is going to be created, allowing it to expose of these in the internal Kubernetes networking.
