Title: Remove update ssh config tasks

Although AWS EC-2 always use key to loggin, but in local deployment, use password to loggin ssh is common. Update the system sshd_config without any warning might cause people can not loggin to their host any more, and that should be a disaster for host manager. It should be more safe to give people manage their sshd_config.
