When we apply a manifest with a 1024Gi storage requirement, it may be internally persisted with a different storage unit (eg. 1Ti). When doing a strict deep equal comparison, 1Ti and 1024Gi are different. A user applying such a manifest will not have any update allowed, even though he keeps using 1024Gi. This fixes it by relying on `apiequality.Semantic.DeepEqual`, which is used in Kubernetes itself: https://github.com/kubernetes/kubernetes/blob/c369cf187ea765c0a2387f2b39abe6ed18c8e6a8/pkg/apis/apps/validation/validation.go#L156

Backport #2857 on 1.1.
