The io/ioutil package has been deprecated as of Go 1.16, see
https://golang.org/doc/go1.16#ioutil. This commit replaces the existing
io/ioutil functions with their new definitions in io and os packages.

Otherwise we had an issue where the file existed with the correct
owner/group; when we rewrote it we set the owner/group to root/root;
but we then didn't set the owner/group if they were previously
correct.
Was visible in the flatcar test results.
We don't call klog.InitFlags yet, because that will cause a flag
redefinition error until we get everyone to stop using glog. That
will happen when we update to k8s 1.13.
This is needed so that we can have encrypted storage and complex keys
(e.g. multiple CA certs). Multiple CA certs are needed for an in-place
upgrade from kube-up v1.
* GCE support only
* Key and secret generation
* "Direct mode" makes API calls
* "Dry run mode" previews the changes
* Terraform output (though key generation not working for master ip)
* cloud-init output (though debian image does not ship with cloud-init)
