Force each process to use its own database connection, add a migration creating relevant switches, and simplify the logic determining whether it's safe to use threads.

ECOM-5871

A Waffle switch can now be used to toggle parallelized execution of the data loading pipeline. The pipeline is structured so that stages that can run independently of others are interleaved using separate processes.

A separate Waffle switch can be used to toggle threaded writes to the database. Instead of using threads to request all data, then writing it all serially, use this switch to spawn separate threads responsible for reading and writing each page of data.
