Add option to background migration helper

What does this MR do?

An option is added to the background migration helper queue_background_migration_jobs_by_range_at_intervals to allow specification of the primary_column_name.

The method uses id by default, but some tables do not have a primary key of id. This MR gives the option to specify a different column, such as project_id.
