Support AWS IAM Roles Anywhere

### What feature do you want to see added?

AWS IAM Roles Anywhere allows workloads such as servers, containers, and applications that run outside of AWS to obtain [temporary security credentials in IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp.html), see https://docs.aws.amazon.com/rolesanywhere/latest/userguide/introduction.html. Is there a plan to enhance this plugin to support this service, i.e. IAM roles anywhere, to obtain credentials to call AWS services, in addition to existing ways of AWS access keys and IAM roles? I assume that this would be helpful, for cases, for example, say a Jenkins cluster running on-premise, though requiring access AWS to handle some CI/CD process?
