Remove `query_id` from NodeBinding

[colleenXu]

This issue is for discussing the removal of query_id from NodeBinding (formal deprecation).

Currently, some members are in favor of removal, recalling...

• in the past, query_id was used for QNode ID subclassing cases: the NodeBinding's query_id would be the original QNode ID, while the the id would be descendant Node that's actually used in the Result.
• that behavior has been replaced by using AuxGraphs: the NodeBinding id is to the QNode ID, and the edge has a support_graph (AuxGraph) with the subclassing edges/descendant Node that's actually used
• so the query_id isn't used for anything

Other members want more discussion, recalling...

• query_id is used for set-input queries?
