Handling Cluster Scoped Primary Resource in Dependent Resource `SecondaryToPrimaryMapper`

[csviri]

Currently by default Dependent Resource assumes that the primary resource is namespace scoped, see:

java-operator-sdk/operator-framework-core/src/main/java/io/javaoperatorsdk/operator/processing/dependent/kubernetes/KubernetesDependentResource.java

Line 90 in 0b17878

return Mappers.fromOwnerReferences(false);

This is something users have to then handle explicitly, by overriding the SecondaryToPrimaryMapper, see:

#2310 (comment)

In DRs we don't have access to the class of primary to check if it is namespace scoped. But we might create some workarounds, like passing it as a flag for managed resources automatically.
