How to use the noop option to check for changes in Satellite config files when running satellite-installer

Issue

• The Satellite 6 installer script is based on Puppet, which means that any manual configuration changes will be overwritten to the installation defaults. You can use the --noop argument when you run the installer script to determine what changes would be applied when you run it. This argument ensures that no actual changes are made.
• Hiera users, in particular, can use this method to check in advance what changes will be made by running the installer script.
