Request: Support AWS Credentials File

[Aghassi]

Currently, the only way to run this script is with secrets. Secrets are not very useful when your company authenticates your AWS accounts via CLI and stores the AWS temp credentials locally.

Suggest changing aws_access_key and aws_secret_key to the following

variables.tf:

// variable "aws_access_key" {
//   description = "Access key used to create instances"
// }

// variable "aws_secret_key" {
//   description = "Secret key used to create instances"
// }

variable "aws_creds_file" {
  description = "AWS Credentials File"
}

variable "aws_profile" {
  description = "AWS Profile"
}

circleci.tf

provider "aws" {
  region                  = "${var.aws_region}"
  shared_credentials_file = "${var.aws_creds_file}"
  profile                 = "${var.aws_profile}"
}

terraform.tfvars

// aws_access_key = "..."
// aws_secret_key = "..."
aws_creds_file = "~/.aws/credentials"
aws_profile = "default"

As an example.
