Passwordless sudo support

This release brings per-user attribute support sudo_without_password: yes - setting it to true will cause to add user to a group sudonopasswd instead of sudo group. In result the sudo su and sudo -u otheruser will be without prompting for a password.
Useful for users used for automatic deployments.

Jails, inline SSH keys
