Have a --settings option

[Gijsreyn]

Summary of the new feature / enhancement

As a user, I want to be able to set the available settings in dsc.settings.json using the CLI. Now I need to read the documentation for the available options, nor is there any schema help for it.

Proposed technical implementation details (optional)

Implement a new command --settings with optional subcommands:

• export: To export the current settings
• set: To set the available settings
• reset: To reset to the default settings

In the set subcommand, perhaps an optional parameter could be added to choose which dsc.settings.json needs to be updated.

We should probably turn the settings to a struct and generate JSON Schema for it. Is there any reason to want to set it via CLI rather than as a DSC resource?

Both are fine for me Steve. Was mainly looking towards WinGet.
