    Extend hiera task to improve plugin support

    * Add hiera_config type to mange hiera.yaml
    * Plugins can put their overrides to /etc/hiera/plugins/
    * Running hiera_config again will gather override files
      and insert records for them to the main config file after
      the basic elements
    * Or, it metadata_yaml_file is present, hiera_config can
      take the list of enabled plugins and add records for them
      instead of scanning the plugins directory

    Closes-Bug: 1512456
    DocImpact: add information about placing plugin data files to /etc/hiera/plugins/ instead of other files.
