Downstream column lineage

[pawel-big-lebowski]

Problem

Column lineage should be able to detect downstream edges when requested.

Closes: #2116

Solution

Extend recursive query, that returns column lineage nodes, to traverse the graph for downstream nodes.

Note: All database schema changes require discussion. Please link the issue for context.
