Review Comment:
Can we add a check to see if `DataManagementService` properly receives the
clean-up messages?

Review Comment:
Is there any reason to start the timer after 1 second?
Since it will delay the deletion of the ETCD key for the problematic
container, another request heading to this container can still come during that
time.
The request will be rescheduled, but it will anyway also delay container
creation.
