Undeploy Nuxeo before services in benchmark

We observe warn logs about not being able to reach Kafka on Nuxeo when the benchmark environment is shutdown.

This is because all pods are undeployed at the same time.

We would like to undeploy the services before Nuxeo, this could be achieved with needs in the helmfile file https://helmfile.readthedocs.io/en/latest/#dag-aware-installationdeletion-ordering-with-needs

To use needs we need to upgrade helmfile in our builders, we currently have v0.138.2, we need at least v0.139.9.
