This configures forwarding from the executor to the worker to cloudwatch. This prepares for removing internet access from the executor. Vector forwarding via the worker is easier than trying to get the executor cloudwatch access through VPC endpoints. The latter would make the secure instance code a lot more complex.
The executor can use this to stream logs via vector.

This is a requirement to remove internet access from the executors entirely, yet keep logging.
Mind that this is just the first step, removing internet access would need to be done after the forwarding has been shown to work properly.
