[#969] node: Do not require shard config in relay mode

Browse source 
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).
