ConnectionDetails Support for Apache Solr

Add ConnectionDetails Support for Apache Solr so that @Serviceconnection works with https://java.testcontainers.org/modules/solr/

Thanks very much for the suggestion. We haven't seen much demand for Solr support in the Spring ecosystem. This led to Spring Data for Apache Solr be discontinued and Spring Boot's support for Apache Solr was removed at that time. Since then, I can't recall any requests to re-introduce support for it so I don't think we can justify adding service connection support at this time. We can reconsider if the situation changes and there's significant demand for it, but until then I'm going to close this one. Thanks again for the suggestion though.
