[ANSIBLE] Setup Prometheus to select all ServiceMonitors

By default Prometheus selects only ServiceMonitors with a "release" label
set to "kube-prometheus-stack" which prevents correct discovery of Onap
monitoring targets. With these settings any ServiceMonitor with any
arbitrary label will be selected.
