[Archival] [s3 provider] use IAM role + serviceAccount

Describe the solution you'd like

• use IAM role + IAM policy
• create serviceAccount with annotation eks.amazonaws.com/role-arn

Additional context

I've tried to configure this, but got an error regarding s3 access
From what I could find in the community, at the moment it is only possible to use IAM user (env vars AWS_ACCESS_KEY_ID + AWS_SECRET_ACCESS_KEY)

I would love to see this feature as well, since it makes sense in an EKS environment to use service accounts and IAM roles over creating users and access keys.
