  NOTE: Until Solr 7.5, cluster properties supported a `collectionDefaults` key which is now deprecated and
  replaced with `defaults`. Using the `collectionDefaults` parameter in Solr 7.4 or 7.5 will continue to work
   but the format of the properties will automatically be converted to the new nested structure.
  Support for the "collectionDefaults" key will be removed in Solr 9.
