Igor Soarez updated KAFKA-15357:
--------------------------------
    Description: 
A new DirectoryEventManager accumulates, batches, and sends assignments or 
failure events to the Controller, prioritizing assignments to ensure the 
Controller has the correct assignment view before processing log dir failures.

Assignments are sent via AssignReplicasToDirs, logdir failures are sent via 
BrokerHeartbeat (delegated to BrokerLifecycleManager).

Broker halts if log dir failure timeout is exceeded before the controller is 
notified of offline dirs.
