Terraform-provider-aws: Changing RDS identifier forces new resource

[hashibot]

_This issue was originally opened by @joshuaspence as hashicorp/terraform#6080. It was migrated here as part of the provider split. The original body of the issue is below._

---

Changing the identifier parameter of an aws_db_instance resource forces a new resource. I think that this is a bug because I can change this field through the AWS console.
