Delete lineage (beta)

This version of the lineage delete API introduces support for an optional dataflow_key parameter.

The request allows deletion of a lineage edge between a source object and a target object.

• If dataflow_key is not provided, the API deletes the lineage edge between the source and target regardless of any associated dataflows.
• If dataflow_key is provided, the API deletes the edge only if it is associated with the specified dataflow and no others.
• If the edge is also associated with a different dataflow, the request is rejected with a validation error.
