(renamed from "actuator")

Many things have changed:
 - Where we had a List of Machine, we now have a YAML stream,
   i.e. multiple documents separated by ---
 - Where we had a single struct, we must deal with a ClusterAPI struct
   and a provider-specific struct

Fix up ParseAndDefaultAndValidate to return both cluster structs

Update build image to Go 1.13.5

So we can treat an error on 'kubectl get nodes' as transient, while
still logging that it happened.

* Update weave-net IPALLOW_RANGE on `wksctl init`

- If you are gitopsing weave-net
- Update wk init cli help

Remove some commented-out mentions of it from scripts

It installs pip for us.
