> Replica / ReplicaInfo should be immutable and their fields should be validated on creation.
> Some users reported that very rarely during a failed collection CREATE or DELETE, or when the Overseer task queue becomes corrupted, Solr may write to ZK incomplete replica infos (eg. node_name = null).
> This problem is difficult to reproduce but we should add safeguards anyway to prevent writing such corrupted replica info to ZK.
