HTTP Server metrics: for some entries, server_address do not correspond to server_name

[mariomac]

Even if server_address and server_name don't have to be equal, for some entries, the values are clearly wrong, for example:

{server_address="grafana-k8s-monitoring-alloy-logs", service="notel-demo-checkoutservice", service_name="notel-demo-checkoutservice"}
{server_address="notel-demo-productcatalogservice", service="beyla", service_name="beyla"}
