hostmetrics and kubeletstats are missing service name and id

[JBodkin-Amphora]

The hostmetrics and kubeletstats receivers don't add a service.name and service.instance.id attribute, therefore when the OpenTelemetry Collector creates a target_info metric, the resource attributes are copied to the new metric and dropped from the scraped metric. This leaves the scraped metric with no resource attributes.

Should these attributes be added in the pipeline using the OpenTelemetry Collector pod name and id?

This seems to be the cause of the issue: open-telemetry/opentelemetry-collector-contrib#27839
