[PATCH v2 05/20] nmbug-status: Add metavars for --config and --get-query

[W. Trevor King]

Now the suggested usage (listed by 'nmbug-status --help') is:

  usage: nmbug-status [-h] [--text] [--config PATH] [--list-views]
                      [--get-query VIEW]

instead of the less obvious:

  usage: nmbug-status [-h] [--text] [--config CONFIG] [--list-views]
                      [--get-query GET_QUERY]
