verbose_name is unnecessary for hidden field

[Akihiro Motoki]

verbose_name is unnecessary for hidden field.
Some verbose_name does not have much meaning (it is just a mirror of form field name) but it is marked as translated and such strings are difficult to translate. One I encountered is in openstack_dashboard/dashboards/project/containers/tables.py.

    metadata_loaded = tables.Column(get_metadata_loaded,
                                    verbose_name=_("Metadata Loaded"),
                                    status=True,
                                    status_choices=METADATA_LOADED_CHOICES,
                                    hidden=True)

metadata_loaded is difficult to translate and there is no need to translate it too because it is invisible in a browser.

I would suggest to delete verbose_name from hidden field.
According to my check, we have only four hidden fields with verbose_name.
it can be easy to clean up.
