Consistent resource naming convetions

The iam.tf file contains two different resource naming conventions:

The ecs_profile resource uses underscores while all other resource names use hyphens (e.g. ecs-role, ecs-policy, etc...).

Can a consistent convention be used throughout? It appears that underscores _ are more common. Happy to submit a pull request if that's the desired approach.

Cheers,
Mike

@watchwithmike done! i've tagged this as v5.0.0 because i haven't verified that the rename is nondisruptive, please lmk whether you run into trouble with this.

PRs are always welcome, but this was pretty straightforward :)
