AWS region as variable

[vadimAnte]

Hello,

Please add AWS region to variables.
Imagine that you are deploying an many AWS regions, but prefer keep all back-end files in one region only.

@vadimAnte I think I like this idea, thanks for the suggestion!

I have three questions.

1. Should the region variable have a default, or just be blank?

2. In the case of "no default", what happens when the variable is unset/blank?

3. Would it not be "better" to encourage users to use the AWS_DEFAULT_REGION variable before plan/apply?

Error: Missing required argument

The argument "region" is required, but was not set.

1. i think you should allow this as a config option in the backend module.

module "backend" {
  source = "github.com/samstav/terraform-aws-backend"
  backend_bucket = "somebucket"
  region = "${var.region}"
}

2. following the steps in the README.md, the module asked me for a region when i ran the plan command terraform plan -out=backend.plan -target=module.backend. after I chose us-east-1, the error above returned. if there's no default set and the user does not set one, allow it to exit 0.

3. yes, i will set and try again using AWS_DEFAULT_REGION.

Thanks @cbfx.

So, expose the region variable but default it to blank?
