Automatic merge from submit-queue Fixing e2e tests which rely on network disruptions **What this PR does / why we need it**: It fixes e2e tests on network disruptions **Which issue this PR fixes** *(optional, in `fixes #<issue number>(, #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes https://github.com/kubernetes/kubernetes/issues/27324, https://github.com/kubernetes/kubernetes/issues/35293 https://github.com/kubernetes/kubernetes/pull/33655 changed the kubelet's `--api-server` flag to use the external IP address of the APIServer in GCE. Hence, the iptables rules were failing previously. We now return the external IP for `getMaster()`. This fix is required in order to write e2e tests which test behavior in the face of network disruptions. /cc @bprashanth @dchen1107 @kubernetes/sig-apps
