=> option-def to define the option 121 has an array of uint8,
option-data with a cut and paste of what you use for ISC DHCP.
Note you can use keama to automatize this...

PS: it is a bit more hairy when you use records: as in Kea the array flag
is for the option there is an ambiguity between an array of records and
a record where the last field is an array so not all ISC DHCP option
definitions can be translated to Kea.
