Fix CSI issue and upgrade to kubernetes 1.14.0

[mavimo]

This PR will update to kubernetes 1.14.0 and fix issue on CSI.

Actually tested with a new cluster, than create a secret with hetzner token:

cat >secret.yaml <<EOF
---
kind: Secret
apiVersion: v1
metadata:
  namespace: kube-system
  name: hcloud-csi
data:
  token: {ADD_TOKEN_BASE64_ENCODED_HERE}
EOF

and deploy all the required stuff:

kubectl apply -f https://raw.githubusercontent.com/kubernetes/csi-api/release-1.13/pkg/crd/manifests/csidriver.yaml
kubectl apply -f https://raw.githubusercontent.com/kubernetes/csi-api/release-1.13/pkg/crd/manifests/csinodeinfo.yaml
kubectl apply -f https://gist.githubusercontent.com/mavimo/399d9f783a59653bac71c8ddbf886757/raw/bc9ff2bcc6c38fea27f2586ce5da0cfa2a6e004e/hetzner-csi.yaml

at the end create a new pod using the PV, eg:

cat >test-csi.yaml <<EOF
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: csi-pvc
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi
  storageClassName: hcloud-volumes
---
kind: Pod
apiVersion: v1
metadata:
  name: my-csi-app
spec:
  containers:
    - name: my-frontend
      image: busybox
      volumeMounts:
      - mountPath: "/data"
        name: my-csi-volume
      command: [ "sleep", "1000000" ]
  volumes:
    - name: my-csi-volume
      persistentVolumeClaim:
        claimName: csi-pvc
EOF;

and deploy it:

kubectl apply -f test-csi.yaml

that's work without issue on logs (I inspected with journalctl -u kubelet on master and worker nodes).
