These settings are no longer configurable on a per-instance basis, so 'delegate to teacher' needs to be removed from the options list for the relevant fields in the tool type edit form. For existing tool types, allow 'delegate to teacher' to continue to be used only if it's the currently set value of these fields. If changed, it cannot be set again.
