Access: Direct RabbitMQ for ECS #1177

Is your feature request related to a problem?
Currently, the RabbitMQ instance in ECS production can be accessed directly. This means the instance is reachable without going through the bastion host, which is not the desired security setup.

Describe the solution you'd like

• Restrict direct access to the RabbitMQ instance in ECS production and place it behind the bastion host.
• RabbitMQ should only be accessible when connected through the bastion. This will ensure that the RabbitMQ instance is not directly reachable via its IP address and that access is controlled through the bastion host.
