k8s-bot: there should be a command to rerun GKE smoke tests only

I wasn't able to find one. cc @eparis @lavalamp

This is actually a jenkins/test-infra thing, not a merge bot thing. @fejta @ixdy

cc @spxtr

Yes please assign to @spxtr (ideally in test-infra repo)

Right now it uses the same command as the GCE test. It's pretty simple to change it, just need to update the regex.

Something like @k8s-bot gke e2e test this where the gke is optional? The same thing could be done for GCE.

sgtm, we have this for node already

Closing in favor of kubernetes/test-infra#269
