Add labels for the lightspeed-app-server service

telemetry-operator creates a ScrapeConfig that collects metrics from
Lightspeed /metrics endpoint. The ScrapeConfig uses a LabelSelector
to discover the Lightspeed service.

Adding "metrics" and "service" labels allows the Lightspeed service
to be discoverable by the ScrapeConfig.
