Ian Campbell 164c4a30f5 kubernetes: support untainting master via metadata ...

If a stamp file is present in the metadata then untaint.

This is useful for dev environments where you only want to start a single vm.

The construction of the metadata becomes a little more complex to produce
correct json syntax now that there are two (independent) possible options.

Likewise the kubelet.sh script now takes the presence of /var/config/kubeadm
(rather than /var/config/kubeadm/init) as the signal to use the more structured
setup, since we may now have /var/config/kubeadm/untaint-master but not
/var/config/kubeadm/init so would otherwise end up passing the contents of
`/var/config/userdata` (something like `{ "kubeadm": { "untaint-master": "" }
}`) to `kubeadm` and confusing it enormously.
