Terraform: AWS Elastic File System DNS name has (silently?) changed

[aisamu]

Hi there!

It turns out, as per the AWS Console and new EC2 mounting instructions, AWS has (silently?) dropped the availability zone from the EFS DNS name.

The former us-east-1a.fs-xxxxxxxx.efs.us-east-1.amazonaws.com becomes just fs-xxxxxxxx.efs.us-east-1.amazonaws.com.

Unfortunately, aws_efs_mount_target.xxx.dns_name still outputs the old format.

For the moment, just dropping the AZ from the DNS works, as in replace(aws_efs_mount_target.xxx.dns_name, "/\\A[^\\.]*\\./", ""), but I figured it'd be useful to let you know!

Thanks a lot for this great tool!

FWIW, this change was discreetly announced last week https://aws.amazon.com/fr/about-aws/whats-new/2016/12/simplified-mounting-of-amazon-efs-file-systems/
