This stops backend traffic before pre-upgrade migrations so the database is not changed while the app is still serving.
Operators need to know the feature is disabled by default, how to enable it, and that it causes backend downtime.
The pre-upgrade hook now stops every database-capable application Deployment and creates temporary namespace RBAC before the migration Job.
