Upgrade kubespray from 2.12.6 to 2.14.1

- Replace move of ansible.cfg from kubespray distribution to
  /etc/ansible with ANSIBLE_CONFIG environment variable.  Ansible
  modifies ansible.cfg during installation, and the paths in it are
  relative.

- kubespray 2.14.1 requires a kubernetes version > 1.16.  Use the
  default versions of kubernetes and helm provided by kubespray
  2.14.1.

- kubespray 2.14.1 replaces helm 2 with helm 3.  This removes support
  for helm init and helm serve.  It is no longer necessary to call
  helm init, and the helm serve repository is replaced with file
  relative URLs.  This also triggered a subsequent update of the
  kubernetes-helm ansible module to include the newer helm versions.

- Add "storageType: hostPath" to etcd/values.yaml.  Helm deploy of
  etcd will fail without this due to nil
  PersistentVolume.metadata.labels.type.

- The mitogen module used by kubespray/ansible requires python2 on the
  hosts.  Use the linear strategy to bypass mitogen and install
  python2 on the cluster hosts.
