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.
