QOL issues with the elasticClusterProvisioning script

[navarro967]

The elasticClusterProvisioning.php script does not currently support setting a source path for elasticsearch mapping files and only pulls them from this repository.

I would like to be able to deploy this locally without relying on GitHub. My suggestion would be to add a flag that can set the path to these files on the local disk and fall back to GitHub if it isn't present.

It would also be beneficial to have this script run unattended, it asks for input to remove files after completing. Rather than piping 'yes' to the script it would be wonderful if it had a -y flag.
