Missed in the transition to Zuul v3, there is no longer a legacy host named "primary" in the Ansible inventory (this was provided for compatibility with pre-v3 Nodepool multi-node topologies). Switch to specifying "all" for the applicable hosts in post playbooks, as there is only one remote node for these jobs anyway so which one they run on is irrelevant.
