Warning: Missing version constraint for provider "aws" in `required_providers` (terraform_required_providers)

Reference: https://github.com/terraform-linters/tflint-ruleset-terraform/blob/v0.7.0/docs/rules/terraform_required_providers.md

If I add

  required_providers {
    aws = {
      source = "hashicorp/aws"
    }
  }

to the terraform block in main.tf, tflint runs cleanly. I would think it should run clean with my initial config as well.

Duplicate of #21. TFLint isn't aware of the idea of passing providers between modules. It's a tricky problem so there hasn't been any movement towards a fix.
