[k8s] Restrict getEndpoints to search only in current pod

* If we have a k8s cluster installed and
   then deploy 2 apps, each on separate pod,
   then in logs we will see 2 endpoints for
   2nd app. Then we will see 3 endpoints for
   next pod/app deployment. The reason is searching
   endpoints was done by whole k8s cluster but it
   should rather be only by current pod.
   Now it is fixed.
