The learner records feature had to be enabled/disabled via site-specific
configuration models, which is inconvenient for platforms that want to
disable this feature globally. Here, we introduce a
ENABLE_LEARNER_RECORDS feature toggle in the lms/cms settings that makes
it possible to disable this feature on all sites. Because this feature
toggle is set to True by default, this will not modify the behaviour of
existing platforms.
* Fix type mismatches in the course_modes migrations
* Fix type mismatches in the course_action_state migrations
* Fix type mismatches in the schedules migrations
* Fix type mismatches in grades migrations
* Fix type mismatches in video_pipeline
* Fix type mismatches in api_admin
* Fix mismatches in credential migrations
To allow the notify_credentials management command to run from a
jenkins job, we want to allow the command to pull its arguments
from the database, rather than the jenkins interface.
So this adds a table that admins can adjust in the DB and a new
argument for notify_credentials to tell it to go look there.

Add some waffle-guarded connection points to the Credentials service
to start filling out the user flow for Student Records.
Specifically, add a button to the Program Progress Details page if
a certificate exists, and add a link in the Learner Profile page.
Both only appear if the 'student_records' waffle switch is active.
