feat!: Upgraded Terraform version to 1.0+. Added wrappers.

Fixed #240

It was not possible to fix elegantly for Terraform 0.13, so upgraded to Terraform requirements to be 1.0.

@antonbabenko what does this due to users who do not use Terragrunt?

[antonbabenko]

Several things. It allows users to work with one module instead of individual, if they prefer, e.g.:

module "alb" {
  items = {
    one = "..."
    two = "..."
  }
  # ...
}

or use fewer duplicated files (terragrunt.hcl) if they use terragrunt or other similar tools like terragrunt where for some reasons for_each is not an option (I saw a custom/legacy wrapper recently).

I use this approach exclusively with terragrunt (S3 bucket and object modules) and it is a life-saver code-saver. Some people use it with our EC2 instance module, and I think it is ok to be used with any other module (if a user wants).

This is rather handy when managing lots of similar smaller resources - IAM users, SNS, SQS, Lambdas, etc.

Wrappers have no extra logic or conditions.
