1. final_snapshot_identifier is an optional argument for the aurora resource object. However, upon destroying the resource, it seems necessary to either provide a name for the final_snapshot_identifier or by setting skip_final_snapshot to true.

2. Can someone unpack the note in the documentation about arguments in terraform including the username and password being stored in the raw state as plain-text.

Instead of adding a solution for securing the login credentials, I've added some documentation in the terraform file to keep the module simple.

It makes sense that way. I production setup we don't want to pass secrets this way because they are then stored in the tfstate file. But for our examples it's what we want (for simplicity).
