    Notify port_update to agent for status change

    Notify agents about port update when "port_update" is called to update
    port's status change. L3 agent will spawn keepalived only when HA
    network port status is ACTIVE. When L3 agent is restarted, it sets HA
    network port status to DOWN (through "port_update"), with the assumption
    that L2 agent will again rewire the port (set status to ACTIVE) allowing
    L3 agent to spawn keepalived. As server is not notifying L2 agent, port
    is remaining in DOWN status and L3 agent was never spawning keepalived
    on L3 agent restart(if keepalived is killed).
