Feature request: Support networkd IPv6 Router Advertisement options

[Michael Atkins]

When I've enabled '
accept-ra' I would like to also configure the options under here:
http://manpages.ubuntu.com/manpages/bionic/man5/systemd.network.5.html#[ipv6acceptra]%20section%20options.

This is so that I can, for example, ignore DNS config given to me by my ISP.

Perhaps this could be taken one step further and abstracted so that any/all networkd section options can be configured with something like:

accept-ra: true
ipv6-accept-ra:
  use-dns: false
  use-domains: false
dhcpserver:
  pool-offset: 10
  pool-size: 24
xxx-section-options:
  option-0:
  option-etc:

Thanks

We have something similar already for DHCP Overrides: https://netplan.io/reference/#dhcp-overrides

Keeping this idea in line with DHCP Overrides, it could result into something like this:

accept-ra: true
ipv6-ra-overrides:
  use-dns: false
  use-domains: false
  table: 42

Pull requests welcome :-)

I do not agree with this idea. It might work if networkd would be the only backend for Netplan. But we also have to consider different backends, like NetworkManager. Therefore, we should not adopt networkd naming 1:1 but rather refine it in a generic way, considering the different backends and options available.
