Comment 1 for bug 1410034

Exactly what 'delete quotas for a tenant' means is not clearly defined, but I think setting them to zero meets one definition.

Putting them to defaults is somewhat counter intuitive - if you delete somebody's quota and they have quota afterwards (might even be *more* quota than before the delete if the defaults are higher than the override) I'd say that was unexpected.

Might be better to add a separate command to give somebody back default quota(s)?
