SolrResourceLoader logging about "Solr home set to" is very missleading/broken in multicore

      Description

      the SolrResourceLoader constructor has this bit of logging left over from the days before multicore...

          log.info("Solr home set to '" + this.instanceDir + "'");
      

      but this is confusing and missleading since there are N+1 SOlrResourceLoaders in a given solr instance (1 for the CoreContainer, and N for the N cores) and only one of them is refering to the true "Solr Home" dir, the others are refering to the instanceDir of the respective cores.

      For example, using the 3.5 example and running java -Dsolr.solr.home=multicore -jar start.jar you'll see...

      we should revamp/add some of the log messages from CoreContainer and SolrResourceLoader to make it more clear what the one true solr home is, and when SolrresourceLoader is being used for an instanceDir of a single core.
