Define alerts for the batched background migration framework
Context:
The batched background migration framework does not have any alert system in place. If something goes wrong during the execution of a batched background migration, we don't receive any notification.
Example: We don't receive any alert if a batched background migration job gets stuck and runs for hours.
Goal:
We should implement an alert system for the batched background migration framework.
