Which issue(s) this PR fixes:

Fixes #
scripts/:

• my_cluster.sh - Ansible configuration
• my_playbook.sh - Kubernetes build tool
  K8s Calico nodes located in gatewayed private network. (hosts.ini)
  Bridged Internet Sharing (docker-DNS)
  Special notes for your reviewer:
  Ubuntu Server should be installed on every Raspberry Pi host as 18.04 LTS/arm64
  Upload kubespray folder to Raspberry Pis and run the configuration scripts/hap-wiz-bionic.sh on each one. Add option --clientfor nodes.
