> Current implementation of {{IgniteLimit}} doesn't  support distribution trait propagation.
> Limit must require singleton distribution.
> Now we cannot reproduce invalid behavior (see IGNITE-12819) and IgniteLimit isn't placed under the Exchange node.
> Also Limit must be propogated (copied) under Exchange to reduce unnecessary fetches.
