New replication task flag: sudo. Controls whether the user used for SSH/SSH+NETCAT replication should use sudo to execute zfs commands on the remote host. (in other case zfs allow must be used to grant non-user permissions to perform ZFS tasks, but mounting ZFS filesystems by non-root still won’t be possible due to the way Linux currently works)

keychaincredential.setup_ssh_connection method that is used in replication wizard also has sudo flag in semi_automatic_setup option. It should only be visible to the user if username is not root. We should note that checking this option will lead to /usr/sbin/zfs being allowed to be executed using sudo without password. And not checking this option will lead to the consequences described above.
