Add tenant uuid when running cinder list --all-tenants

Add the tenant uuid to the output when running cinder list --all-tenants,
since this is an admin command any way, it would help to list the tenant
UUID so we do not have to run cinder show to see the tenant uuid when we
have further queries to run.
