support curveadm daemon

[caoxianfei1]

curveadm目前支持ssh方式登录到远程主机，但是由于一些原因可能无法提供ssh密钥对。
我们希望可以通过daemon的方式，实现通过http访问服务器，中控机以http的方式发送请求。

Hello, I am a graduate student majoring in computer technology at Hangzhou University of Electronic Science and Technology. My commonly used development language is go. I have participated in the Douyin back-end development project of the Byte Youth Training Camp. I am also familiar with the stack (gin, grpc, docker, k8s, mysql, redis, etcd). I hope to participate in a project on this theme and learn about distributed storage.
