Test external_dns_ha_flat failed on executing command: "ntpdate -s vip_ip"
http://paste.openstack.org/show/203617/

after some time command finished with successful exit code
http://paste.openstack.org/show/203721/

The cause of the issue is that the controller node is not ready to provide time right after reverting.
Time synchronization methods should be updated.

    Force ntp on controllers work faster

    As long as standard NTP divergency time floats between 8-20 minutes,
    this time can be easily improved. What's changed:

    * add iburst - send packets with less interval if server unreachable
      after first sended packet
    * add tinker panic 0 - time can be stepped a lot
    * add tinker stepout 5 - time can be stepped a lot many times and fast
    * add minpoll 3 - minimal upstream poll interval now 8s
