Public bug reported:

In the instance detail page, the description field is only shown when
the description of a corresponding server has non-empty string. It is
better to display "description" field regardless of its value.

[detail]
Nova API returns 'null' (python None) for description field if no description is set for the server.
The current _detail_overview.html checks {% if instance.description != None %} but it leads to a confused situation.

I guess this was introduced to support an older nova APi version without
description support, but there is no good way to distinguish no
description field and empty description. There is also no good way to
handle False and None separately in django template filter (without
creating a new attribute like has_description). Having a new attribute
like has_description works but I think it is too much, and the recent
releases of nova support description field, so no check looks needed.
