Helm chart does not propagate commonLabels to pods

[ejstreet]

What happened:
When setting commonLabels in the helm chart, the labels are not applied to pods, despite the description saying labels will be applied to "all chart resources".
What you expected to happen:
commonLabels should apply to pods, either by being included directly or using one of the helper wrappers in the pod template of the deployment.
How to reproduce it (as minimally and precisely as possible):
Set commonLabels. Pods do not get given labels.
Anything else we need to know?:
Minor issue, can be worked around by additionally setting podLabels.

Environment:

• External-DNS version (use external-dns --version): n/a
• DNS provider: n/a
• Others: Helm Chart
