Fixes:#10902
AWS introduced a change to the Mount Target DNS Name to remove the
availability_zone from it -
https://aws.amazon.com/about-aws/whats-new/2016/12/simplified-mounting-of-amazon-efs-file-systems/
This was because there used to be a limit of 1 mount target per AZ -
this has been raised.

* Handle missing EFS mount target in aws_efs_mount_target.
This commit resolves issue where the EFS mount target would be already
deleted (e.g. it was deleted outside of Terraform, etc.). Also, correct
how values are begin set in the ReadFunc to avoid nil pointer dereference.

* Add acceptance test to check for non-empty plan.
This commit adds a test to verify the condition where the underlying EFS mount
target would be deleted and/or disappear resulting in a new resource to be
created to replace it.
