What this PR does / why we need it:
During installation of Loki Operator it creates multiple services pointing to the operator used for different purposes. The
ServiceMonitorused for getting metrics from the operator contains a selector that currently matches more than one of these services. This causes Prometheus to generate multiple targets for the same operator instance, leading to duplicate metrics.This PR fixes this issue by adding an explicit "metrics label" to one of the services and updating the
ServiceMonitorto just match that specific service.Which issue(s) this PR fixes:
LOG-5212
