* [fix] Certificate availability date cleanup
This task will clean out the misconfigured certificate available date. When courses Change their
certificates_display_behavior, the certificate_available_date was not updating properly. This is
command is meant to be ran one time to clean up any courses that were not supposed to have
certificate_available_date
[refactor] change backfill date task to long running task
Change from a task that spins off multiple other tasks to a single long
running task. This will hopefully be way less heavy when this is ran in
production.
* [refactor] Move backfill_date_for_all_course_runs to Tasks.py
In order for celery to register this task, it needs to be in the right
file. duh!
* fix imports
* fix more imports
Before this change, the notify_credentials management command ran for
about 10-15 minutes and occasionally overlapped with an edxapp
deployment which would cause the machine the command was running
on to die. The command ran through a bunch of certs and grades, and then
spun off celery tasks to send the relevant data to credentials.
Now, most of the logic of the notify_credentials management command has
been moved into a new celery task, so that combing through longs lists
of certs and grades is done asynchronously. This task then spins off the
original data-sending tasks as before.
Note that this requires a change in alerting: where the jenkins job
would previously notify us about failures, we need to know when this
new celery task fails for any reason. We’ve made this a LoggedTask
so that failures will be logged to Splunk and alerting can be built off
of the error messages.
This commit also moves the relevant tests.
