kubefed init returns: Cannot parse dnsName "apiserver.federation-system.svc.cluster.local."

[Knappek]

I guess kubefed has a bug. When I execute

kubefed init federation-test --host-cluster-context=gke-andy-test --dns-zone-name="federation.andy.test." --dns-provider="google-clouddns"

I get the error

Creating a namespace federation-system for federation system components... done
Creating federation control plane service.............. done
Creating federation control plane objects (credentials, persistent volume claim)...error: failed to create federation API server key and certificate: unable to sign the server certificate: x509: cannot parse dnsName "apiserver.federation-system.svc.cluster.local."

This seems to be related to this issue: kubernetes/ingress-nginx#2188.
