### Description
Hi,
There is mandatory parameter iam_role_name parameter for GlueJobOperator/GlueJobHook.
It adds additional step of translating it to the arn, which needs  connectivity to the global iam AWS endpoint (no privatelink availabale).
For private setups it needs opening connectivity + proxy configuration to make it working.  
It would be great to have also possibility to just pass directly iam_role_arn and avoid this additional step.
### Use case/motivation

Role assignation does not need external connectivity, possibility of adding arn instead of the name.
