Provision cross-device FL cloud infrastructure

Example of a cross-device federated learning workflow
TODO:

• Add Kubernetes manifests to a different PR
• Resolve any linter errors
• Create a module under the /terraform folder
• Use CFT modules

@laurentgrangeau Can you please split this PR into smaller ones? Let's focus on the cloud infrastructure in this one. You can open a draft one for the workloads that we'll review once we merge this one.

Once you do that, please fix any linting errors the lint job reports.

Thanks!

Hi @laurentgrangeau !

A few preliminary comments:

• Can you refactor this to be a module under /terraform that a user can conditionally enable with a variable? That would greatly simplify this PR because you don't need to redefine providers and some data sources.
• Can you refactor this to use Cloud Foundation Toolkit modules?

Thanks!

Everything should be fixed now. Please let me know if everything is good

Hi @laurentgrangeau! I completed a first review pass.

Can you please include a README for the module that describes what it does? We're also going to need to extend the main README with a section (or point to a dedicated document) that explains what we're adding.

Back to you :)

@laurentgrangeau can you also rebase this branch on top of the latest main? There is a fix for container image builds. Thanks!

Small things to check and we should be there.
