> In a multisharded node environment we were seeing forward-to-leader hops when using CloudSolrServer
directUpdate (with the hop being on the same node) . Consequently, there was no improvement
in indexing performance over non-directUpdate. 
> Changing buildUrlMap to use getCoreUrl eliminated the extra hop and now we see a dramatic
improvement in performance.
