This variable can be entirely derived from grains.cloud, and it
simplifies the configuration somewhat. (Or someone convince me I'm
wrong. I'm happy to be wrong here.)
It looks like api_servers finally won this battle. Kill off the
last remaining places passing it, but allow the kubelet Salt to
accept apiservers for a period of time.
(This was bothering my OCD.)
Also fix up cert generation. It was failing during the first salt highstate when trying to chown the certs as the apiserver user didn't exist yet. Fix this by creating a 'kube-cert' group and chgrping the files to that. Then make the apiserver a member of that group.
Fixes#2365Fixes#2368
apiserver becomes kube-apiserver
controller-manager -> kube-controller-manager
scheduler and proxy similarly.
Only thing I promise is that right now hack/build-go.sh and
build/release.sh exit with 0. That's it. Who knows if any of this
actually works....
