PS: if you go to https://www.iana.org/assignments/bootp-dhcp-parameters/bootp-dhcp-parameters.xhtml the option code 150 has 3 different definitions: this is why Kea does not
consider it as a standard option...
Note at a few exceptions an option must be requested by the client. There
is a flag "always-send" to force the server to send an option even when
the client does not request it.
