Justin Pomeroy 407c17b38a Tolerate service catalog and endpoint connection errors
This is a fix for the issues encountered when a service is not
configured or a service endpoint is not reachable. This fix
will add tolerance for these errors so that an error message is
displayed but the dashboard page will still load, not an error page.
This makes it easier for the user to recover by allowing them to
go to a different page, select a different region, or logout. This
makes sense in many cases such as when a region only contains an
image service endpoint, or when a single endpoint is not reachable
for whatever reason.

It also adds permissions to the panels that require compute or
image services so that the dashboard will not display them if
the service is not configured.

To test these changes you will need to set up your keystone service
catalog so that not all services are available in all regions, or
some of the service endpoints are not reachable.
