Description

The current code org.apache.solr.cloud.autoscaling.ComputePlanAction#getNodeAddedSuggester only sets COLL_SHARD hint, as a result any added replica will be NRT one.

Our current setup has TLOG nodes on physical hardware and PULL nodes on k8s that are recycled periodically. An attempt to add those will bring the nodes in the cluster as NRT one.

The root cause is org.apache.solr.client.solrj.cloud.autoscaling.AddReplicaSuggester#tryEachNode that expects to find the hint REPLICATYPE and defaults to NRT one.
