In the django/contrib/admin/options.py, I see that opts reference is
available in the template context of changelist_view, delete_view,
render_change_form, etc. but however not in history_view. We have a
simple scenario where we override the object_hostory.html and need
access to Model's _meta to access the model options.

I think that perhaps opts should be available in history template as
it is available on most other admin pages.

Any reason that this might be a bad or perhaps incomplete idea as I'd
like to go ahead and create a ticket.
