Description

currently if you run an example command and the core/collection being created already exists you get an error message in the console, ut then the example keeps working (see below).

I think it would be better if the script used the cores api (or collection api in the 'cloud' example) to check if the collection already existed, and if so just output a note about it, something like...

Core API indicates a core named 'techproducts' already exists...
http://localhost:8983/solr/admin/cores?action=status&core=techproducts

To remove this core, use the following command...
  bin/solr ...etc...
And then you can recreate it with...
  bin/solr ...etc...

Current behavior...

...
Creating new core 'techproducts' using command:

http://localhost:8983/solr/admin/cores?action=CREATE&name=techproducts&instanceDir=techproducts

Exception in thread "main" org.apache.solr.client.solrj.SolrServerException: Request to http://localhost:8983/solr/admin/cores?action=CREATE&name=techproducts&instanceDir=techproducts failed due to: Core with name 'techproducts' already exists.
