ExtractNamespace extracts the namespace of ObjectMeta.
For cluster scoped objects the Namespace field is empty and this function
assumes that the object is returned from kubernetes itself implying that
the namespace is empty only and only when the Object is cluster scoped
and thus returns empty namespace for such objects.
GetObjNamespaceName returns the object's namespace and name.
If the object is cluster scoped then the function returns only the object name
without any namespace prefix.
GetServiceListOptionsModifier returns the options modifier for service object list.
This methods returns a ListOptions modifier which adds a label selector to only
select services that are in context of Cilium.
Like kube-proxy Cilium does not select services containing k8s headless service label.
We honor service.kubernetes.io/service-proxy-name label in the service object and only
handle services that match our service proxy name. If the service proxy name for Cilium
is an empty string, we assume that Cilium is the default service handler in which case
we select all services that don't have the above mentioned label.
