      Create the LSP of the migration target pod with enabled=false.

      Flip this to enabled=true; flip the source pod LSP enabled attribute to false.

      This will be our fallback solution for seamless live-migration in case FDP-770 turns out to be impossible / require further OVN changes / proves too "big" to be accomodated in 4.18.

      This should go into 4.18 to improve migration downtime for both primary / secondary UDNs.

      The PoC code is available in https://github.com/qinqon/ovn-kubernetes/tree/poc-kv-live-migration-lsp-enabled
