unnecessary reconcile because of dependent HPA resource

[andrascz]

Using the 0.8.0 version of the plugin.

I have a helm chart with HPA resources in it. While no change is made on the HPA resource, still a reconciliation is triggered, because when comparing old and updated, the metadata.managedFields.["subresource" == "status"].time field differs.

The status and metadata.resourceVersion fields are already removed before comparison. I think the object with subresource == 'status' should be also removed from metadata.managedFields before comparison.
See: https://github.com/operator-framework/helm-operator-plugins/blob/v0.8.0/pkg/internal/predicate/predicates.go#L72

I am not sure if fixing by this would be correct.

	unstructured.RemoveNestedField(old.Object, "metadata", "managedFields")
	unstructured.RemoveNestedField(updated.Object, "metadata", "managedFields")
