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

k8s.pod.phase allows to report the pod phase in its lifecycle, however it does not give enough information to report the phase of each container when the pod has more than 1 container running. An additional metric should be available to report the phase for each container

Describe the solution you'd like

Implement either k8s.container.phase in k8sclusterreceiver or add a resource attribute k8s.container.phase in target_info

Describe alternatives you've considered

This will need to be added as a Semantic Convention as well but looks quite similar to the situation's of open-telemetry/semantic-conventions#1181

This change also bring back the age old issue with how do we actually do enums :/ Ref #24425
