Review comment:
If the user-provided ConfigMap only contains a key for the log4j2.xml,
then the operator will create the default ConfigMap for solr.xml, resulting in
this structure in the STS for a SolrCloud named `dev`:
```
volumes:
- configMap:
defaultMode: 420
items:
- key: solr.xml
path: solr.xml
name: dev-solrcloud-configmap
name: solr-xml
```
The `if configMapInfo[util.SolrXmlFile] == "" {` is just how we know there
wasn't a `solr.xml` in the user-provided ConfigMap at that point. Does that
sound right?
