    A new config option ``resync_throttle`` has been added for Neutron DHCP
    agent.
    This new option allows to throttle the number of resync state events
    between the local DHCP state and Neutron to only once per
    ``resync_throttle`` seconds.
    Default value for this new option is set to 1 and it should be configured
    per a user's specific scenario, i.e. how responsive the user would like
    his/her system to be for those DHCP resync state events.
    The option is introduced together with the event driven periodic task for
    DHCP agents. This enhances the agent with a faster reaction on the resync
    request but ensuring a minimum interval taken between them to avoid too
    frequent resyncing.
