A service instance.

It can be helpful to distinguish service Kubernetes data (e.g., my service Pod is running in this cluster that started experiencing issues) from trace data (e.g., requests against some Kubernetes cluster were slow).

The semantic conventions don't provide any guidance in this respect.

Should they?

For example, a service could have a service.instance.k8s.node.name.
