vip-manager 2.5 service cannot remove VIP when etcd is unavailable

[dongsc1994]

Hi~
I found that the vip-manager 2.5 service cannot remove vips when etcd is unavailable. It always responds with state is true, desired true. So should this problem to be solved?

[root@hac156 ~]# /usr/bin/vip-manager --config=/etc/default/vip-manager.yml --verbose

And VIP is not auto removed.

This is vip-manager.yml

[root@hac156 ~]# cat /etc/default/vip-manager.yml

Looking forward to a reply.
