Developer Curb Appeal: Eliminate the need to run Solr example once in order to unpack needed files

In the SolrCloud instructions it says you must run the solr in the example directory at least once in order to unpack some files, in order to then use the example directory as a template for shards.

Ideally we would unpack whatever we need, or do this automatically.

Doc reference:

See the red box that says:
"Make sure to run Solr from the example directory in non-SolrCloud mode at least once before beginning; this process unpacks the jar files necessary to run SolrCloud. On the other hand, make sure also that there are no documents in the example directory before making copies."
