BOM-291

Refactor CSME id, CSMH_EXTENDED default true

* make link_program_enrollments atomic per user

The program course enrollment overview endpoint says
it has a field 'course_status' with a possible value 'in-progress'.
Update it to say it has a field 'course_run_status with a
possible value 'in_progress'.

ProgramCourseEnrollments were already unique on
(program_enrollment, course_enrollment) by nature of the
OneToOneField on course_enrollment. However, this only
affects realized enrollments. For waiting enrollments, we
need to add a uniqueness constraint on
(program_enrollment, course_key).
