improving the aesthetics of the config generation script
No longer overrideing the SCRIPTPATH variable when sourcing the generator.
Fixed issue with the relative paths which resulted in failing to fetch the config file if it already existed.
When asking for the ip of the controller, the script also outputs the ips of the current node in case you are installing the controller.
Forcing user to execute installation with root or sudo
Changing over to the new relative path snippet
Removing the section that tells the user to enter the relevant password when installing the database because we now automatically pass this variable into the installation.
Telling the user to select "no" for configuring services as the script should do everything for them.
Updating the relevant search/replace logic for debian which is slightly different to ubuntu
