Implement Add-on activity log

[ParthS007]

Proposed changes

closes #10053

Add AddonActivityLog model

• Foreign key to Addon
• Foreign key to Component to see what component triggered that event.
• Event to see what action triggered that (some add-ons can be triggered by more of them)
• Timestamp
• Details as JSONField
• Create new instance on each add-on trigger
• Make add-ons log what they did
• Add a renderer for details to the BaseAddon class (subclasses might customize this)
• List paginated events delivery on add-on management page
• Add pruning of events after some time

Checklist

Add pruning of events after some time

What is the criterion for pruning and how we plan to do this?

1. Have a management command to delete events
2. Have a task scheduled after a certain interval to prune automatically.

[nijel]

Have a periodic task for that, something similar like we do for an audit log:

weblate/weblate/accounts/tasks.py

Lines 38 to 45 in f61fea6

	@app.task(trail=False)
	def cleanup_auditlog() -> None:
	"""Cleanup old auditlog entries."""
	from weblate.accounts.models import AuditLog
	AuditLog.objects.filter(
	timestamp__lt=now() - timedelta(days=settings.AUDITLOG_EXPIRY)
	).delete()

[nijel]

I'd display the activity log on the add-on detail page, not on the list page. On the list page, all add-ons logs would be mixed up, what could make reading the log challenging with many add-ons installed.

Looks good now, the only missing bit is ability to display log for add-ons which have no configuration.

[nijel]

Can you please add test for the new view?

[nijel]

Can we have tests that the request for logs fails without authentication?
