Relay storage node doesn't exec local object operations, so it doesn't need shard configuration. Add `required` bool parameter to `engineconfig.IterateShards`. Make it to panic if it is `true`, and immediately return otherwise. Pass `false` if node is configured as relay in app (it also prevents panic). Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
