  https://github.com/openvswitch/ovs/commit/dfc3e65c8191f5dc375337c23aed128b5c0d7781(2.17 branch patch)

  Testcase:
  Trigger compactions by using command line tool:
  ovs-appctl -t /var/run/ovn/ovnsb_db.ctl ovsdb-server/compact
  Check for leadership transfers using:
  sudo grep "Transferring leadership" /var/log/ovn/ov* | grep ovsdb-server-sb.log
