* Auto-CLI enhancements

* A generated clispec including state (default @datanodestate) also generated along with the config clispec tree (default @datanode)
  * New mode `GT_HIDE` set by option `CLICON_CLI_GENMODEL_TYPE` to collapse non-presence containers that only contain a single list
  * Added a prfix for cli_show_config/cli_show_auto so that it can produce parseable output
  * Thanks dcornejo@netgate.com for trying it out and suggestions
