Comment 2 for bug 1749209

IIUC, those haproxy, dnsmasq, keepalived and radvd are not the neutron agents' child processes, right? I'm recalled with ironic HA topic, where that was exactly tha case, thus asking. If those used to be just system daemons, we should implement those as a separate containers running within the neutron agents "pods". K8s pods, once we're there and just containers sharing Linux namespaces et al otherwise.
