usage_description="
Creates an AWS terraform service account for Terraform Cloud or other CI/CD systems to run terraform plan and apply

Grants this service account Administator privileges in the current AWS account unless a different group or policy is specified as a second argument

Creates an IAM access key (deleting an older unused key if necessary), writes a CSV just as the UI download would, and outputs both shell export commands and configuration in the format for copying to your AWS profile in ~/.aws/credentials

The following optional arguments can be given:

- user name         (default: \$USER-terraform)
- group or policy   (default: Admins group if found, else AdministratorAccess standard AWS-managed policy)
- keyfile           (default: ~/.aws/keys/\${user}_\${aws_account_id}_accessKeys.csv) - be careful if specifying this, a non-existent keyfile will create a new key, deleting the older of 2 existing keys if necessary to be able to create this

Idempotent - safe to re-run, will skip creating a user that already exists or CSV export that already exists

Examples:

    # creates user 'github-actions-MYREPO' with full AdministratorAccess and saves the key in ~/.aws/keys/

        ${0##*/} github-actions-MYREPO

    # creates a read-only user 'github-actions-MYREPO-readonly' with ReadOnlyAccess standard AWS-managed policy attached for GitHub Actions environment secret that can be automatically used in Pull Request workflows without approval, saves key to ~/.aws/keys/

        ${0##*/} github-actions-MYREPO-readonly ReadOnlyAccess
