When user specifies labels in the template section, they should be propagated even when they are app.kubernetes.io labels (or at least some of them). For example in this case:
template: statefulset: metadata: labels: app: spring-music-cdc app.kubernetes.io/part-of: spring-music-cdc template: spring-music-cdc
Here the app.kubernetes.io/part-of label should be propagated to indicate what application is this part of. This should not apply to any strimzi.io labels which are our own.
