Setup a task queue - celery, django-q, huey

[sarahboyce]

We should be sending emails in tasks and we could do with some cron jobs around notifying when applications for sessions start.

From my preliminary research:
One option is to create a crontab on every deployment. Another is to use Azure Functions with a timer trigger. Or we could use celery with another app service instance.

If we go for the cron option, we need something like this for sending emails: https://nemecek.be/blog/158/django-how-to-send-email-without-celery 🤔

It could work?
