Review Comment:
The primary consequence of misclassifying requests is that it changes how
the requests are routed in `CloudSolrClient` due to this [code
block](https://github.com/apache/solr/blob/af97ef7037aec0c1fb028e173b6d8931cd12588d/solr/solrj/src/java/org/apache/solr/client/solrj/impl/CloudSolrClient.java#L1027-L1134).
If an `ADMIN` request is routed like a non-ADMIN request, or vice-versa, the
result is a 404 when using this client. My apologies for not being more
specific about this.
The root cause of the problem seems to be that `ADMIN` endpoint URLs are
constructed this way:
```java
final var nodeBaseUrl = Utils.getBaseUrlForNodeName(liveNode, urlScheme);
requestEndpoints.add(new LBSolrClient.Endpoint(nodeBaseUrl));
```
while typical endpoint URLs are constructed this way:
```java
String joinedInputCollections = StrUtils.join(inputCollections, ',');
final var endpoints =
preferredNodes.stream()
.map(nodeName -> Utils.getBaseUrlForNodeName(nodeName, urlScheme))
.map(nodeUrl -> new LBSolrClient.Endpoint(nodeUrl,
joinedInputCollections))
.collect(Collectors.toList());
```
So request type is being used to determine whether or not to include the
name of the collection in the final endpoint URL.
