Ability to use different labels for Deployment's `spec.template.metadata.labels`

Currently The same values field podinfo.selectorLabels is used for both spec.selector.matchLabels AND spec.template.metadata.labels. I'd like to be able to set a label in spec.template.metadata.labels without it also appearing in spec.selector.matchLabels

My recommended resolution would be to create a new values.yaml field called podinfo.podLabels

It may also help to add some documentation that podinfo.labels doesn't label the pods that the deployment creates, just the deployment itself.
