Exclude Elasticsearch and Solr Auto Configuration from Registry

The NiFi Registry web application uses Spring Boot to load a number of standard configuration objects. The default behavior attempts to configure a Solr Client and an Elasticsearch Client when the corresponding client libraries are on the class path. Although these libraries are not present in that standard NiFi Registry build, the include-ranger build profile incorporates these libraries as transitive dependencies.

The Spring Boot configuration for NiFi Registry should be updated to exclude these configuration classes to avoid unexpected runtime behavior when including the Apache Ranger plugin.
