Changes
Summary
- refs: #8700: downgrading spring, solr, solrj, compiler, and httpClient dependency versions to what's in the 2.3 branch and production. Changes made across the d1_cn_common, d1_cn_index_common, d1_cn_index_generator, and d1_cn_index_processor components. There is a refactored HttpSolrClient construction method that needed refactoring. Downgrading loses the builder in favor of the "new" method.
