Volunteer preferences and notifications

[ryanwilsonperkin]

Request from volunteer:

Would it be possible to introduce a system where delivery volunteers can set preferences for distance, city, time of day, and number of people, and be notified when requests matching the criteria pop up? It would be very helpful to help volunteers deliver more regularly.

This would be a bit tricky to get right but should be possible. We don't have a task runner but for periodic tasks we can use Heroku's scheduler to run a script periodically. That could call a management command that would find requests for recipients and send out notifications. The tricky bit would probably be ensuring that we don't send the same message multiple times. Maybe just something that we send out once a week on monday, kinda like a newsletter.
