  - Merge "[ovn][metadata] Remove metadata readiness mechanism"
  - [ovn][metadata] Remove metadata readiness mechanism
    
    Prior to this patch, the metadata agent was writing into SB
    database when a network had been provisioned with metadata
    on a particular chassis.
    
    Then, neutron-server would wait for that event to happen with
    a 15s timeout before sending the vif-plugged event to Nova.
    
    By removing this mechanism:
    
    1) We'll save writes to OVN SB database which, in highly loaded
    systems and at scale reduces significantly the load on ovsdb-server.
    
    2) Ignoring healthchecks (that still requires write to the SB DB),
    we can make OVN metadata agent to connect to slave instances when
    using active-backup OVN databases since writes are not needed.
    
    3) There's a chance that the VM boots very fast and requests
    metadata before the service is ready but since the timeout was
    15 seconds, we can safely rely on the the cloud-init retries.
