Description

TopicPartition is used as the key when computing the local changes in TopicsDelta. The topic id is included in the Map value return by localChanges. I think that the handling of this code and the corresponding code in ReplicaManager could be simplified if localChanges instead returned something like

{
  deletes: Set[TopicIdPartition],
  leaders: Map[TopicIdPartition, PartitionRegistration],
  followers: Map[TopicIdPartition, PartitionRegistration] 
}
