ReplicaPlacement (Solr 9.0.0 core API)

```
public interface ReplicaPlacement
```
Placement decision for a single Replica. Note this placement decision is used as part of a PlacementPlan, it does not directly lead to the plugin code getting a corresponding Replica instance, nor does it require the plugin to provide a Shard instance (the plugin code gets such instances for existing replicas and shards in the cluster but does not create them directly for adding new replicas for new or existing shards).
Captures the SolrCollection, Shard (via the shard name), Node and Replica.ReplicaType of a Replica to be created.
