Enable OVN-native BGP in bgp_dt01

Replace ovn-bgp-agent with neutron-ovn (OVN agent) for BGP support:
- Add ovn-bgp neutron service plugin to control plane configuration
- Add neutron-ovn-extra-config ConfigMap with OVN agent BGP extension
- Replace neutron-metadata and ovn-bgp-agent EDPM services with neutron-ovn
- Remove edpm_ovn_bgp_agent_* ansible variables (no longer needed)
- Update README.md services table
