services.openssh: support freeform settings (#193757)

* 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" ])
