feat: support labels key in transformer configuration (#5556)

Browse Source 
* feat: support labels key in transformer configuration

Allow the usage of a separate transformer configuration for the labels key,
similar to what is currently available for commonLabels and commonAnnotations.
This aims to provide the same functionality that commonLabels currently provide
for labels, since commonLabels is deprecated and slated for removal in a future
release.

* chore(transformerconfig): add nolint hint

Add a nolint hint to the new method so the returns can stay consistent with
one another.

* fix: changes from code review

* Rename methods `AddCommonLabelFieldSpec` and `AddLabelFieldSpec` to
  `AddCommonLabelsFieldSpec` and `AddLabelsFieldSpec`.
* Add extra test to verify scenarios applying labels to Custom Resource Definitions.
