Okay, so shall we add it in generic Plan node or to specific plan nodes
like SeqScan, IndexScan, etc.  To me, it appears that parallelism is
a node specific property, so we should add it to specific nodes and
for now as we are parallelising seq scan, so we can add this flag in
SeqScan node.  What do you say?
