Add support for the `-from-module` flag when init

[samerbahri98]

SUMMARY

Terraform has a feature where it can initialize a working directory from a terraform module like this:

terraform init -form-module <module>

The ansible cloud.terraform.terraform module does not support this unfortunately. And it would be nice if this feature exists.

  cloud.terraform.terraform:
    project_path: '{{ project_dir }}'
    state: present
    from_module: terraform-iaac/nginx-controller/helm  # this should download https://registry.terraform.io/modules/terraform-iaac/nginx-controller/helm/latest

@samerbahri98 Thanks for opening on issue. My understanding is that this feature is primarily intended for use with Terragrunt (see https://github.com/hashicorp/terraform/issues/33276#issuecomment-1568546030), and I'm not sure it's something we would want to support. What's the use case for this?

I also have interest on this feature

ah sorry @gravesm I forgot to reply. The use case here is that I use ansible to perform system integration tests. I used the example of the official terraform registry in the issue description, but the actual modules are in different git repositories and s3 buckets, and I would like to skip the steps of downloading the modules and putting them in a wrapper module to test them.
