Support requiring providers within tests

[wyardley]

Terraform Version

Terraform v1.9.5
on darwin_arm64

Use Cases

Similar to https://github.com/hashicorp/terraform-provider-assert/issues/48 I'd like to use a module specific to tests (that one), but not have it as a dependency of the module I'm testing.

As of now, this requires some pretty ugly hacks like mocking and initializing an extra "module", since terraform { required_providers }} can't be set in the test configs.

Attempted Solutions

in tests/main.tftest.hcl:

provider "google" {
  project = "foo-testproject"
}
variables {
  foo = "bar"
}
terraform {
  required_providers {
    assert = {
      source = "hashicorp/assert"
    }
  }
}
run "basic" {
  command = plan
  plan_options {
    refresh = false
  }
  assert {
    condition = ....
  }
}
