Description

There are a few bits of the code from SOLR-10007, SOLR-8906 that could stand some cleanup. For instance, the TransientSolrCoreCache is rather awkwardly hanging around in CoreContainer and would fit more naturally in SolrCores.

What I've seen so far shouldn't result in incorrect behavior, just cleaning up for the future.
