    Update OVN_AGENT_METADATA_SB_CFG_KEY when OVN metadata agent starts
    
    If the metadata agent is not present in the local AgentCache and the
    report time (agent_down_time) is too long, the Neutron API will delay
    the Chassis_Private update. As a result, the agent will not update the
    corresponding record properly. Consequently, the newly added metadata
    agent will not appear in the output of the openstack network agent
    list command.
    
    This patch aims to update OVN_AGENT_METADATA_SB_CFG_KEY to nb_cfg as
    soon as the metadata agent starts.

Title:
  openstack network agent list cannot return new added metadata agent

Status in neutron:
  Fix Released

Bug description:
  Summary
  * If the agent_down_time is set to a large value, openstack network agent list might not return newly added metadata agents

  Reproduction Steps
  * Set agent_down_time in neutron.conf to 2147483 in large cluster
  * Add new compute nodes
  * OVN controller started -> chassis & chassis_private (external_ids={}) recorded created in ovn sb db
  * Neutron metadata agent started -> update chassis_private external_ids neutron:ovn-metadata-id with agent_id
  * run "openstack network agent list" command

  Expected output:
  * New added "OVN Metadata agent" will be returned

  Actual output:
  * New add "OVN Metadata agent" won't return

  Version:
  * stable/2024.1
  * master
