confd: dns srv function is not perfect

Firstly, -srv-domain doesn’t support _etcd-client-ssl._tcp.example.com which is etcd dns srv with ssl. Even if I use -scheme https

Secondly, when I use -srv-record _etcd-client-ssl._tcp.example.com -scheme https to replace, it shows

It seems that -scheme doesn’t work.

Finally, I use -node and it connects successfully. But it tells me that key doesn’t exist, because confd prepends / to my key automatically, even if I set prefix = "" in toml.
