This addresses a longstanding TODO item to make runtime.anonymous_student_id for content libraries v2 work the same way as it does for XBlocks in regular courses, persisting the "context ID" (equivalent to course ID) to the database. This way, if SECRET KEY is changed, existing anonymous IDs will continue to work unchanged. This is a potentially breaking change, but should mostly affect capa problems using external code graders or Matlab code input, and I'm not aware of any such usage of the new runtime / libraries v2.
