* services.openssh: support freeform settings Keep "extraConfig" but introduces "settings". Also renames several options (mkRenamedOptionModule [ "services" "openssh" "kbdInteractiveAuthentication" ] [ "services" "openssh" "settings" "KbdInteractiveAuthentication" ]) (mkRenamedOptionModule [ "services" "openssh" "passwordAuthentication" ] [ "services" "openssh" "settings" "PasswordAuthentication" ]) (mkRenamedOptionModule [ "services" "openssh" "useDns" ] [ "services" "openssh" "settings" "UseDns" ]) (mkRenamedOptionModule [ "services" "openssh" "permitRootLogin" ] [ "services" "openssh" "settings" "PermitRootLogin" ]) * updated doc * regen doc
