Research: Steps needed for OpenTofu Support

[GoodmanBen]

Current State

OpenTofu has come out with an alpha 1.6 release. It is said to be a drop-in replacement for Terraform, and some percentage of the market of Terraform users may be splitting to follow the fork.

Desired State

Explore the lift needed to support OpenTofu. This includes answering questions like:

• How is OpenTofu use specified within cloud-concierge configuration?
• How are different versions of OpenTofu dynamically downloaded. As of right now cloud-concierge is reliant on tfswitch which has an open issue asking for open tofu support: OpenTofu Support warrensbox/terraform-switcher#315
• Distinguishing need to run tofu init and tofu state update commands within the container execution

Hi @GoodmanBen,

At this moment if you need to have a support of Terraform as well as OpenTofu (and Terragrunt :) ) in one tool you can use https://github.com/tofuutils/tenv which my team wrote some months ago. A lot of users switched to that tool to unify version management in the world of Terraform.

You're welcome to open any issues or contribute to tenv. I think it will be really suitable for this issue to manage different versions of different tools.
