Why do you need this resource or plugin? Please describe.

We need to scan the public ssh keys of an IAM user in order to identify potential security risks caused by public keys that are not rotated.

Describe the solution you'd like

It should be straight forward to include the IAM resource model AwsIamSshPublicKey using ListSSHPublicKeys call from IAM service.
