    Description

      As a precursor to IMPALA-4224, we should add a mechanism for an finstance to discover the join build sink from another finstance.

      We already have a related single-purpose mechanism in the coordinator to find PlanRootSink. We should generalise this to allow looking up the sink of any other finstance and move it into QueryState
