Public bug reported:

Description
===========
One of the goals of cells is to allow nova scale and to have cells as failure domains.
However, if a cell DB goes down nova doesn't list any instance. Even if the project doesn't have any instance in the affected cell. This affects all users.

The behavior that I would expect is nova to show what's available from
the nova_api DB if a cell DB is not available. (UUIDs and can we look
into the request_spec?)

Steps to reproduce
==================
Have at least 2 child cells.
Stop the DB in one of them.

"nova list" fails with "ERROR (ClientException): Unexpected API Error."
Not given any more information to the user.

Expected result
===============
List the project instances.
For the instances in the affect cell, list the available information in the nova_api.

Actual result
=============
$nova list
fails without showing the project instances.

Environment
===========
nova master (commit: 8d21d711000fff80eb367692b157d09b6532923f)
