Gateway Task Does not Allow for create_iam_role=false or custom_security_group_ids #322
Description
The gateway-task submodule does not provide a way to disable IAM role creation and thus providing my own IAM Role ARN.
The gateway-task submodule also does not provide a way to supply it with my own security group IDs for the ECS service/task, only allowing for creating an LB security group and nothing more (which seems mesh gateway specific, but is not very helpful if your kind is terminating-gateway).
