Public bug reported:

Environment:
- OpenStack Release: 2025.1 (Epoxy) / Neutron 26.0.0
- OS: Ubuntu 24.04 LTS
- Backend: RabbitMQ for RPC

Issue:
neutron-metadata-agent appears as XXX (dead) in `openstack network agent list` despite:
- Service being active and running (systemctl status shows active)
- Metadata functionality working correctly for instances
- [agent] section configured with report_interval = 30
- log_agent_heartbeats = true shows no actual heartbeat attempts in logs

Expected: Agent should show :-) (alive) status
Actual: Agent shows XXX (dead) status

Configuration tested:
- Verified RabbitMQ connectivity
- Confirmed Nova metadata service reachability
- Checked hostname resolution
- Verified other agents (L3, DHCP, OVS) report correctly

This appears to be a state reporting implementation issue specific to
the metadata agent, as it doesn't seem to be sending RPC heartbeat
messages despite configuration.
