    [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.

Title:
  TestHAL3Agent.test_ha_router_restart_agents_no_packet_lost fullstack
  fails

Status in neutron:
  Fix Released

Bug description:
  I saw that sometimes TestHAL3Agent.test_ha_router_restart_agents_no_packet_lost fullstack test fails because there is really packet lost after agent's restart.
  Example of such failure is on: http://logs.openstack.org/70/574370/1/check/neutron-fullstack/804a4fa/logs/dsvm-fullstack-logs/TestHAL3Agent.test_ha_router_restart_agents_no_packet_lost.txt.gz#_2018-06-11_21_26_57_858

  What I saw in logs is that after L3 agent restart there are some
  warnings: http://logs.openstack.org/70/574370/1/check/neutron-
  fullstack/804a4fa/logs/dsvm-fullstack-
  logs/TestHAL3Agent.test_ha_router_restart_agents_no_packet_lost/neutron-l3-agent
  --2018-06-11--21-26-43-905027.txt.gz#_2018-06-11_21_27_04_621

  Such warnings are not observed when test runs fine.
