Feature: Custom DHCP/BOOTP options for Kea DHCP

[Codelica]

Is your feature request related to a problem? Please describe.

In migrating from ISC DHCP to Kea DCHP one feature is still missing for me -- the ability to add custom DHCP/BOOTP options. (As defined here). For example I'm using option 43 (Vendor Specific Information) to assist in adoption of new Ubiquiti network equipment. Kea seems to have the ability documented here.

Describe the solution you like

The ability to add custom DHCP/BOOTP option similar to the current ISC DHCP interface.

Describe alternatives you considered

Giving up and staying with ISC DHCP until it no longer is offered. :)

Additional context

That's it, thanks for considering!

same as #7361 (comment) ?

Wow, sorry I didn't think to search the PRs. That would definitely take care of my need, and looks more elaborate than the current ISC DHCP/BOOTP options implementation -- where you just add raw number, type, value combinations. I'll just follow that issue. Thanks!

@Codelica no problem, on our end we just were not able to reach a functional state, we kept the code in a separate branch. When we know what the [kea] configuration should look like and there are people confirming it actually works, it shouldn't be a huge deal to finish the work.

There is Kea 1.6.0 in the pipeline, but I'm a bit reluctant to pull this in for 24.1.x. It might change things, but it might also bring new issues.
