Replace commonLabels with labels

[JoeyC-Dev]

Proposed change:
Replaced the deprecated commonLabels with labels

Supporting point:
Currently, if executing the following command, the error will pop:

VERSION=v0.49.1
kustomize build "https://github.com/google/cadvisor/deploy/kubernetes/base?ref=${VERSION}" | kubectl apply -f -
# Warning: 'commonLabels' is deprecated. Please use 'labels' instead. Run 'kustomize edit fix' to update your Kustomization automatically.

Justification of the change:
In my consideration, both includeSelectors and includeTemplates are not needed. It does work without using them. But the behaviour of commonLabels (referring to old method) will use includeSelectors and includeTemplates mandatory, while these are not necessary at all.
If the team believes includeSelectors and includeTemplates are needed, please comment so and I will add them.
