dpvs-agent api可以获取通过api创建的vip，不能获取通过keepalvied管理的vip #1045
Description
OS: Rocky Linux 8.10 (Green Obsidian)
Kernel: Linux 5.10.134-18.an8.x86_64
dpvs-1.10.1 ，编译时启用dpvs-agent，vip是通过keepalived进行管理的,
ipvsadm -ln -t 10.33.180.114:80
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 10.33.180.114:80 wlc
-> 10.69.8.130:80 FullNat 100 43 50
-> 10.69.10.178:80 FullNat 100 47 45
-> 10.69.12.243:80 FullNat 100 45 56
启动dpvs-agent，通过接口查询/v2/vs获取未空 (通过调整url snapshot=false参数也不行)
strace日志如下:
strace -f -e trace=read,write ./dpvs-agent
