[Feature] Declarative file based configuration for e.g. automation

[Bjego]

Description of the new feature/enhancement

Hey guys, from a dev perspective it would be great, if we could have a declarative, config file based install/uninstall command to install all of our dev teams tools with one command.
The declarative approach should be able to install new applications, update existing ones and also to uninstall no longer needed programs as well.

Proposed technical implementation details (optional)

I could think of a command like :
bash winget targetState ./config.yml
where config.yml could be:

- app: Git
  version: x.Y.z
- app: VSCode
  version: c.V.A
- Visual Studio Enterprise
- PowerShell
- Dotnet Core SDK

Take a look at the export import issue #220. The schema used for this feature will likely provide exactly what you're looking for.

@denelon is right this seems to be a duplicate of these tickets #155 #156 and their duplicate #220. Those tickets are already planned in milestones (https://github.com/microsoft/winget-cli/milestone/8). So this can be closed I guess.
