SOLR-7280: refactored to incorporate Mike's suggestions. Default thread count for cloud is
limited to 8 now. In our internal teting 8 has given us the best stability during restarts

> In SOLR-7191, Damien mentioned that by loading solr cores in a sorted order and tweaking
some of the coreLoadThread counts, he was able to improve the stability of a cluster with
thousands of collections. We should explore some of these changes and fold them into Solr.
