Set service.name and service.version

`service.name` should use value from the label `app.kubernetes.io/name`
first, and then fallback to the `kubernetes.container.name` if not
present. I need to double-check if I can use the container name as is
of I need to parse it in some form.

`service.version` use value from the label `app.kubernetes.io/version`,
if present.
