rancher: use a zfs dataset for /var/lib/kubelet to use the local storage for EmptyDir volumes

Vincent Sellier requested to merge generated-differential-D8482-source into generated-differential-D8482-target

A manual reconfiguration of the existing nodes will be needed to configure the dataset beforepuppet does a mount over on the existing directory content
