RBM+VRRP主备场景主设备上下行接口联动RBM状态切换DOWN

大致组网如下，两台防火墙做RBM+VRRP主备，上行接一台其他厂商设备，当RBM发生切换时，该厂商业务流量转发无法立即刷新，希望通过直接断开GE0/2接口的方式实现业务切换。RBM控制VRRP主备切换，不会联动接口物理、协议DOWN，现行主流版本也无法track启用vrrp的物理接口、进行监控联动DOWN，可以通过EAA方式实现需求。

管理主的相关配置：
RBM_P[H3C-rtm-liandong]dis th
#
rtm cli-policy liandong
event syslog priority all msg "RBM running status changed to standby" occurs 1 period 100
action 0 cli system-view
action 1 cli interface GigabitEthernet1/0/2
action 2 cli shutdown
action 3 cli quit
action 4 cli interface GigabitEthernet1/0/4
action 5 cli shutdown
user-role level-3
user-role network-operator
user-role network-admin
#

测试效果：

主设备检测到“RBM running status changed to standby”事件，实现联动接口down。此时，RBM和VRRP主已经切换到了RBM管理备机，由于管理主机的接口已经down，备机无法通过手动切换RBM状态的，需要手动undo shutdown联动接口，才可以正常回切。

RBM管理备机无法通过手动切换RBM状态的，需要手动undo shutdown主管理设备的联动接口，才可以正常回切。
