Is your feature request related to a problem? Please describe.

I would like to do some aggregations on Kubernetes Pod QOS class using k8sclusterreceiver.

Kube State Metrics has a metric:

kube_pod_status_qos_class{class="Guaranteed|Burstable|BestEffort"}

I would like to have a similar feature, but instead we could add it as resource attribute. Users then could use transformation processor to make it a standalone metric.

Describe the solution you'd like

I suggest we add:

k8s.pod.qos_class optional (disabled by default) resource attribute, with one of the values Guaranteed|Burstable|BestEffort

Describe alternatives you've considered

Sounds like a reasonable addition as an optional resource attribute. @TylerHelmuth @jinja2 WDYT?

Sounds good
