ECOM-5680

Exclude unpublished programs from the course run endpoint

We currently include unpublished programs on the course run endpoint by default.  This change will change that default behavior
so that unpublished programs aren't presented unless the 'include_unpublished_programs' flag is set as a query string parameter.

ECOM-6013

Add swagger comments for the get call view as well

Exclude deleted programs from course and course_run api

Originally, the associated programs array in the course and course_run api object would include all programs regardless of status. With this change, the deleted programs are filtered. Only the query string parameter include_deleted_programs will list out all associated programs

ECOM-5802

Forking processes with open database connections can lead to some surprising behavior! This change forces the parent process running the refresh command to reconnect to the database before making any queries in case one of its child processes has closed the connection it relies on.

ECOM-5871

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.

ECOM-5871

Created dashboard for publisher.
