Add column to control table that determines data extract behavior

[chris-koester-db]

Currently the only behavior is to run queries using Lakehouse Federation. Adding support for bcp and Redshift's UNLOAD requires a new column that controls the data extract behavior.

Todo

• Add a column called extract_type with allowed values query, unload, and bcp.
• Pass this value into a notebook that extracts the data using the specified behavior
• If behavior is other than a query, data needs to then be inserted into the target table
