Powershell script for configuring ML services on SQL (#29)
The script allows configuring ML services on SQL Server
Assumption is that SQL server is already installed with ML services.
You should copy this script on the SQL server machine and run it in admin mode.
This script does the following
1. Enable external script execution on SQL Server
2. Restart SQL server and related services
3. Ensure that launchpad service is running and it set to automatic mode
4. Tries to create login for SQLRUserGroup if not present already.
