I believe it would be more helpful if the logstash date filter [documentation](https://www.elastic.co/guide/en/logstash/current/plugins-filters-date.html#plugins-filters-date-add_field) for `add_field` contains values that are pertaining to `date` rather than `"Hello World, from %{host}"`.

Thoughts?

The `add_field` option (and several others) are present in all filters and the same help text is reused everywhere. Creating custom examples for each filter would be a lot of work with very little benefit.
