I just merged a PR last week from @ihmccreery that added this but it looks like it was taken out when @brendandburns simplified the instructions to use k8s.io. :/

LGTM.

It's actually trying to install it automatically, so we don't need the
instructions. We just need to add an echo in verify prereqs saying what's
going on.

It's trying to install it automatically, but it's failing. Here's the output when I use https://get.k8s.io:

If you're going to make it install automatically you need to somehow make gcloud preview do it - it's not doing it today. (I tried just adding --quiet and it didn't work for me.)

You can definitely do it with -q, and you should be able to override it
with an env variable, though I just noticed the KUBE_PROMPT_FOR_UPDATE
stuff is also busted, too, I think, because it's never accepting the
variable from the outside (it's always "y")? On phone right now, though.
