Comment 8 for bug 1255136

I don't think the fix is complete, or the docs update is inaccurate, as the can_set_mount_point default was only changed in the local_settings.py example file.

If the setting isn't defined, it still defaults to True: see https://github.com/openstack/horizon/blob/2b23ddebcb/openstack_dashboard/dashboards/project/volumes/forms.py#L293 .
