The OpenTofu Grain

OpenTofu is a fork of Terraform that is open-source, community-driven, and managed by the Linux Foundation. Since it's forked from terraform, the 2 grains structure and syntax are similar. You can use any element in the Terraform grain also for OpenTofu grains.

The main difference is the grain kind:

grains:
  database:
    kind: opentofu
    spec:
      source:
        store: 
        path: 
      ...

The rest of the syntax and structure is identical to the terraform grain.
