Connect lineage between datasets
Record that these datasets, and these columns, feed this one.
Added to whatever the dataset already has — an edge that is already there is not duplicated, and one nobody mentioned is not removed. Every dataset and column is checked against the catalog first: an edge naming a column that is not there is stored happily by DataHub and then drawn by nothing.
A column edge implies its table edge, so naming only columns is enough.

The access token received from the authorization server in the OAuth 2.0 flow.
Body
application/json
Edges to add to, or remove from, one dataset.
upstreams are table-level edges; column_edges are the
fine-grained ones. A column edge implies its table edge, so naming
only columns is enough.
