Svcwatcher shouldn't try and deal with Endpoints, Pods, Services, and DanmEps which are not in the same namespace as the changed object

However currently this is unoptimized, and it does.
This is dues to using generic Lister K8s client go API: https://github.com/kubernetes/client-go/blob/kubernetes-1.11.10/listers/core/v1/service.go#L31
rather than the NamespaceLister one: https://github.com/kubernetes/client-go/blob/kubernetes-1.11.10/listers/core/v1/service.go#L33

it does not result in functional error, but can generate misleading error messages, and unnecessary event processing
