🛑 Breaking changes 🛑

• pkg/service: Remove service_name, service_instance_id, and service_version as constant labels on every internal metric datapoint. These attributes are already present in target_info and were being duplicated on each series for OpenCensus backwards compatibility. (#14811) Previously, the collector stamped every internal metric series (e.g. otelcol_process_runtime_heap_alloc_bytes) with service_name, service_instance_id, and service_version labels to match the old OpenCensus behavior. These attributes are now only present in the target_info metric, which is the correct Prometheus/OTel convention. Users who filter or group by these labels on individual metrics will need to update their queries to use target_info joins instead.
