Add email notifications for create, update, and delete events #412
Description
The API endpoints can be easily extended to issue user notifications when create, update, or delete actions are taken against various records. Which notifications a user receives can be determined by user notification preferences.
Here are some suggestions for notifications off the top of my head. Group notifications are mostly intended for admins.
| Record Type | Create | Update | Delete |
|---|---|---|---|
| Group | Yes | Yes | |
| Grant | Yes | Yes | Yes |
| Publication | Yes | Yes | Yes |
| Allocation Request | Yes | Yes (specifically for approval) |
Because the admin panel bypasses the API endpoints, this should be implemented after #300
