Terraform 0.8.x compatability

[cristobal23]

Has anyone tried this module with terraform versions 0.8.x? I got a invalid backslash escape sequence error on generate-certs/main.tf when using terraform 0.8.0

Error loading Terraform: Error downloading modules: module cert_generator: Error loading .terraform/modules/f128a8f9a1d97e66282f11571b6e3f70/generate-certs/main.tf: Error reading config for aws_iam_role_policy[s3_certs_rw]: parse error at 11:50: invalid backslash escape sequence

hashicorp/terraform#8709 looks like related to the fix rolled out for this. Explained here hashicorp/hcl#150. Backslash escapes are ignored inside of ${}.

# line 49
 "arn:aws:s3:::${replace(var.s3_bucket,"/(\/)+$/","")}"

Thanks for the feedback @disaac! I tested the patch in #10 by running bundle exec rake as shown in circle.yml.
