No import users ala aws-ec2-ssh ?

This package is linked from https://github.com/widdix/aws-ec2-ssh as a replacement:
```
June 2019: Check out Amazon EC2 Instance Connect as a replacement for this project
```
However there's one component I don't see here - the bulk import of IAM users into local users onto the AWS linux instance.

Is there some other mechanism that is intended to handle that function, or is this package intended solely to provide access using a single user ID, ie: `ubuntu` or `ec2-user` depending on your linux variant?

The issue references aws-ec2-ssh and EC2 Instance Connect but names no files, tests, or entry points. First clarify whether bulk IAM-user import into local Linux users is required, then identify the relevant instance scripts and packaging configuration; done means the intended mechanism and supported behavior are documented or implemented.
