    Purge deleted /etc/hosts entries for deleted ndoes

    Deleted nodes now will get stored in a file
    /etc/hiera/deleted_nodes.yaml and be inserted into
    the hiera hierarchy.

    host entries for any records present in deleted_nodes.yaml
    will be purged when evaluating hosts task.

    The source YAML for deleted nodes is generated on master
    because nodes that are deployed from scratch or from Error
    state will not be able to identify deleted nodes due to
    certain orchestration limitations.
