Gyu-Ho Lee 45c86af0eb etcdctl/command: mk command with PrevNoExist
This attempts to fix #3676. `PrevNoExist` checks if the key previously exists
and if so, it returns an error, which is how `mk` command is supposed to work.
The previous code ignores the previous key and overwrites with the later value.
