deployment label on ReplicaSet (Pod?) metrics

[IncandescentChrysalis]

What would you like to be added:
deployment label on ReplicaSet metrics, potentially Pod.

Why is this needed:
As of today, it is impossible to aggregate Pods based on a Deployment they belong to.

Describe the solution you'd like

Potentially related to the feature #2424, which addresses objects relationship through dedicated metrics.
The path taken is different, but would also allow for the current use case.
