Comment 9 for bug 1366168

The same result is occured with a deleted public flavor or when a private flavor become inaccessible for the instance project.
For all cases Nova reports the flavor id and doesn't crash. The failure occures in novaclient side.
Nova reports the id always, even when the flavor exists and is accessible.

Similar cases could occure with an instance image. But novaclient properly handles these, though Nova returns only image id as well.

So i propose to fix this in novaclient and do nothing for Nova.
