Upgrade Notes
----------------------
* 'autoAddReplicas' feature is ported to autoscaling framework. Existing users of this feature should not have
to change anything. Note these changes:
1. Behaviour: Changing the autoAddReplicas property from disabled to enabled using MODIFYCOLLECTION API
no longer replaces down replicas for the collection immediately. Instead, replicas are only added
if a node containing them went down while autoAddReplicas was enabled. The params
autoReplicaFailoverBadNodeExpiration and autoReplicaFailoverWorkLoopDelay are no longer used.
2. Deprecations: Enabling/disabling autoAddReplicas cluster wide with the API will be deprecated; use
suspend/resume trigger APIs with name='.auto_add_replicas' instead.
* SOLR-11195: shard and cluster metric reporter configuration now requires a class attribute.
If a reporter configures the group="shard" attribute then please also configure the
class="org.apache.solr.metrics.reporters.solr.SolrShardReporter" attribute.

* SOLR-11254: the abstract DocTransformer class now has an abstract score-less transform method variant.
* SOLR-11283: all Stream Evaluators in solrj.io.eval have been refactored to have a simplier and more
robust structure. This simplifies and condenses the code required to implement a new Evaluator and
robust structure. This simplifies and condenses the code required to implement a new Evaluator and
makes it much easier for evaluators to handle differing data types (primitives, objects, arrays,
lists, and so forth). (Dennis Gove)
