Description

The "userfiles" feature is relatively obscure and might be subsumed by the "file store".  I don't think an obscure feature should be auto-creating its "userfiles" directory.  Even a popular one; not sure it makes sense.  If a user wants to use this feature, they are welcome to create the directory.  Solr has other optional directories, like solr-home/lib that are not auto-created; it's not clear to me why this one is.  I've found the auto-creation of this dir to be annoying in two ways.  One is in Solr's tests – there are existing Jira issues that show stack traces about this even though it's ignored.  Secondly is as a down-stream consumer for running/building Solr plugins that have a Solr home dir pointing somewhere that suddenly has this userfiles dir popping up despite me having no plans to use it.
