Support Credentials from IAM Roles Anywhere

[garciap2g]

Is your feature request related to a problem? Please describe.
When I using credentials from IAM Roles Anywhere, I'm unable to use Cloudwatch Agent, since in OnPrem mode it looks for hard-coded Access Keys in the .aws config files

Describe the solution you'd like
I'd like to use the standard IAM Roles Anywhere service, or the credential_process.

Additional context
I've persued the "RUN_WITH_IRSA" config mode, but this is very poorly documented and also doesn't seem to solve the issue.

Thanks, created a ticket on our internal ticket tracker.

Can you share logs or any artifacts showing it not working as you expect so we can reproduce and triage

Here are the logs if I set credential_process for the[AmazonCloudWatchAgent] profile in config(using iam roles anywhere creds helper)
