func EnsureOwnerReference 

func EnsureOwnerReference(dependent metav1.Object, owner *metav1.OwnerReference)

EnsureOwnerReference adds owner if absent or syncs owner if already present.

If you are writing a controller or an operator, use the following code snippet for dependent objects. Here, `controller = true` and `blockOwnerDeletion = true`

owner := metav1.NewControllerRef(foo, samplev1alpha1.SchemeGroupVersion.WithKind("Foo")) EnsureOwnerReference(dependent, owner)

If our CRD is not a controller but just want to be a owner, use the following code snippet. Here, `controller = false` and `blockOwnerDeletion = false`

owner := NewOwnerRef(foo, samplev1alpha1.SchemeGroupVersion.WithKind("Foo")) EnsureOwnerReference(dependent, owner)

To understand the impact of `blockOwnerDeletion`, read: - https://kubernetes.io/docs/concepts/workloads/controllers/garbage-collection/#foreground-cascading-deletion - https://github.com/kubernetes/apimachinery/blob/v0.17.0/pkg/apis/meta/v1/types.go#L297-L323
