User Story

We want to move to Rabbit 4.1.x to avoid https://git.speag.com/oSparc/osparc-infra/-/issues/70 incidents. There is a x-death header breaking change.

Evaluate if this breaking change affects us. If it does, update the code accordingly. New code must also work with rabbitmq version 3.13 as AWS-managed Rabbit does not support verson 4.0 yet (see aws rabbit documentation)

1. dead letter queues logic works for both 3.13 and 4.1 rabbitmq versions

PS the 4.1 rabbit image will be introduced in ITISFoundation/osparc-ops-environments#1119
