Add generation of azure static CCM pod to bootstrap

[Danil-Grigorev]

The PR would allow to create Azure static pod to bootstrap node. The pod would look like so:

apiVersion: v1
kind: Pod
metadata:
  name: azure-cloud-controller-manager
  namespace: kube-system
spec:
  priorityClassName: system-node-critical
  hostNetwork: true
  containers:
    - name: cloud-controller-manager
      image: mcr.microsoft.com/oss/kubernetes/azure-cloud-controller-manager:v1.0.0
      imagePullPolicy: IfNotPresent
      command: ["cloud-controller-manager"]
      args:
        - --cloud-provider=azure
        - --controllers=cloud-node # run cloud-node controller only for Node initialization
        - --kubeconfig=/etc/kubernetes/secrets/kubeconfig
        - --cloud-config=/etc/kubernetes/configs/cloud.conf # cloud config is generated by https://github.com/openshift/cluster-cloud-controller-manager-operator/pull/55
        # and copied to /etc/kubernetes/bootstrap-configs by bootkube.sh https://github.com/openshift/installer/pull/4947
        - --leader-elect=false
        - --port=10267
        - -v=2
      livenessProbe:
        httpGet:
          path: /healthz
          port: 10267
        initialDelaySeconds: 20
        periodSeconds: 10
        timeoutSeconds: 5
      volumeMounts:
      - name: secrets
        mountPath: /etc/kubernetes/secrets
      - name: configs
        mountPath: /etc/kubernetes/configs
  volumes:
  - name: secrets
    hostPath:
      path: /etc/kubernetes/bootstrap-secrets
  - name: configs
    hostPath:
      path: /etc/kubernetes/bootstrap-configs

Azure CCM require cloud config flag. The file would be unpacked and delivered to the pod by the implementation in #55
