We discover the kops-controller in gossip mode using seeding code that
calls into the GCE API, just like gossip itself does.
We refactor the gossip code into a shared gcediscovery library with
minimal dependencies.
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.

In some scenarios (e.g. cilium), we rely on the internal DNS name
being available, but this isn't the case with gossip clusters.
nodeup can seed /etc/hosts for the control-plane nodes, breaking the
deadlock.

Missed a few
When we have multiple writers racing to write /etc/hosts, we could
have file corruption where we see a mix of both files.
We can't use a traditional atomic file write, because we are bind-mounting /etc/hosts.
Instead we write to /etc/hosts, pause, then re-read the contents. If
the contents don't match, we repeat. This will not result in fair
queuing, but will avoid corruption.
