Comment 1 for bug 1667679

This is because checking for the validity of the project_id was recently added to nova with this patch https://github.com/openstack/nova/commit/f6fbfc7ff07b790ef052a759552c69429b3d79c7 However, it seems that it's tied to using keystone v3, while it should be using the keystoneclient's functions and attempt to be version agnostic.
