Yup, so the user who invokes starcluster will have access to the IAM
user account.

And the correct way to use IAM is to create the IAM user, then select
the user by checking on the check box, go to the "Security
Credentials" tab, and click "Manage Access keys", and "Create Access
keys", then "Show User Security Credentials". Put that Access Key ID &
Secret Access Key in the SC config file instead of that of the AWS
root account.
