Internal Server Error on exceptions from APIs in Overview page

[Rob Raymond]

The Project overview page makes neutron api calls outside of a try, except block. This results in Internal Server Error.
This defect is to fix that problem, but also walk through all of the panel code and add exception handling whenever api call is made.

Any progress? It is worth be a part of Icehouse release.

It can be easily reproduced by stopping neutron-server and then accessing Overview page.
This is the traceback: http://paste.openstack.org/show/75145/
