Bug Description

当运行3到5天左右，偶发出现，会发现proxier会报错：
new [p2p_xxx] already exist!
此时需要杀掉frps，然后重启frps，否则proxier永远无法注册proxies，导致隧道无法使用，影响正常使用。

上述情况已经出现两次，怀疑是frps实现proxies掉线后没有注销掉，导致proxies二次上线被判定重复进而拒绝了注册~！

我也发现这个问题了，不过过一阵子会恢复然后连上。
怀疑是某些启动脚本使用 SIGKILL 信号杀frpc进程引起的。我在梅林固件上发现shell脚本写的是killall -9 ，kill -9这些，我现在在前面使用默认信号先杀一次，杀不掉再用-9。或者使用start-stop-daemon 默认信号停止。
正常停止服务，frpc会有日志 gracefully shutdown visitor manager出现，这样就很好
