packer validate hungs when using amazon resources and no creds are set

[kikitux]

Hi Packer team

packer validate hungs when using amazon resources and no creds are set

Can we add a note to the documentation, or see if packer should exit as won't be able to validate?

repro

{ 
  "variables": {
       "aws_access_key": "",
       "aws_secret_access_key": ""
   },

  "builders": [
    {
      "type": "amazon-ebs",
      "access_key": "{{user `aws_access_key`}}",
      "secret_key": "{{user `aws_secret_access_key`}}",
      "region": "us-west-2",
      "source_ami": "ami-0e32ec5bc225539f5",
      "instance_type": "t2.micro",
      "ssh_username": "ubuntu",
      "ami_name": "ec2_xenial_packer_{{timestamp}}"
    }
  ]
}

Hey @kikitux yes, this is annoying, I'm currently doing a PR in https://github.com/aws/aws-sdk-go/pull/2298 to fix this; but this requires me to do some test with go 1.5 ( which doesn't run on my mac, so I'm debugging with ... travis-ci 😇 ).

But I'm getting there; hang tight !

I recently merged https://github.com/hashicorp/packer/pull/7032 which should prevent this from happening during validation; we'll have to wait for the AWS pull to get merged before we can mark this as totally resolved.
