    [Fullstack] HA L3 agent restart only standby agents

    In fullstack test which is testing if there is no packet lost
    during restart of agents there were restarted always all agents
    which hosted router.
    In case when as first was restarted 'master' agent it might
    lead to the case when after restart 'master' node was switched
    to second L3 agent and that caused lost of few packets and
    failed test.
    This test should only check if restart of standby agents will
    not cause any packet lost so this patch do it in this way.
