Ideally we should add platform_name to int__mitxpro__programs and int__mitxpro__courses since courses_platform is just a lookup table. Otherwise we would need join courses_platform when using courses/programs intermediate models.

Please help me understand this one. Should we add the platform name in the course/program tables? The issue explicitly mentions adding a new table for the platforms just for reusability purposes.

I am not sure what reusability the issue is referring to. Intermediate models are mostly denormalized tables where we join multiple tables together so they can be used by self or by mart.

I don't think it matters that much, just one less table to join in the mart or BI when querying intermediate courses/programs as end user would want the name not internal id.
So you don't have to add the platform name in this PR, we can add that later when working on the mart
What are the relevant tickets?
Fixes the last part of mitodl/mitxpro#2698
Description (What does it do?)
Adds staging and intermediate models for courses_platform in xPro. Also, it updates the staging and intermediate models course/program.
How can this be tested?
