Introduce a nightly maintenance command to handle recurring housekeeping tasks #6590
Description
Proposed Changes
Add a new management command (e.g. manage.py housekeeping) intended to be run nightly. This can take care of recurring tasks such as:
- Deleting expired changelog records
- Clearing out expired auth sessions
- Recording usage statistics (for future purposes)
The installation and upgrade documentation will be updated to include creating a cron job to run this command nightly.
Justification
This would allow us to offload the pseudo-random clearing of expired changelog records from the middleware (see #6056), and provide a foundation for similar additional uses in future releases.
