missing yaml files in 'Deploy without Helm' instructions

The following yaml files referenced in the 'Deploy without Helm' instructions are missing:

https://raw.githubusercontent.com/estafette/estafette-gke-node-pool-shifter/master/rbac.yaml
https://raw.githubusercontent.com/estafette/estafette-gke-node-pool-shifter/master/kubernetes.yaml

Where can we find these files?

Thanks,
