kubeadm: use 'gce' when dumping logs

I0204 22:19:38.408] E0204 22:19:38.408486    1865 test_context.go:430] Unknown provider "kubernetes-anywhere". The following providers are known: aws azure gce gke kubemark local skeleton

seems to me like the log dump is coupled with e2e and that's why it fails.
my last bet is to modify this line to be "gce" instead of "kubernetes-anywhere"

@neolit123 assume we need a global bump to fix CI as well?

[neolit123]

@krzyzacy yep kubetest needs a bump.

[krzyzacy]

on it

[neolit123]

didn't work:
https://gubernator.k8s.io/build/kubernetes-jenkins/logs/ci-kubernetes-e2e-kubeadm-gce-master/1813

I0206 04:33:44.549] Conformance test: not doing test setup.

i do not know where kubernetes-anywhere is coming from at this point.

also logdump started failing after this patch.
https://k8s-testgrid.appspot.com/sig-cluster-lifecycle-all#kubeadm-gce-master

so using gce in log-dump doesn't work even if it seems to me like kubernetes-anywhere is treated the same.

[krzyzacy]

@neolit123 maybe instead of relying on k8s bash, we can try our homebrew e2e and dump packages? :-)

ok, i'm going to try to use these:

W0206 14:32:06.535] JENKINS_GCE_SSH_PRIVATE_KEY_FILE=/workspace/.ssh/google_compute_engine
W0206 14:32:06.535] JENKINS_GCE_SSH_PUBLIC_KEY_FILE=/workspace/.ssh/google_compute_engine.pub

as private/pub key for fetching the logs.

and try the log dumping as implemented in kops.go:

test-infra/kubetest/kops.go

Line 452 in e0cf221

func (k kops) DumpClusterLogs(localPath, gcsPath string) error {
