[PATCH proxmox-ve-rs v4 07/47] frr: implement routemap match/set statements via adjacent tagging

[Stefan Hanreich <s.hanreich@proxmox.com>]

Previously, the types used a mix of adjacent / internal tagging and a
nesting of types to represent match and set statements. This has been
simplified by utilizing adjacent tagging on the set / match statements
and using the exact FRR configuration key as the tag. This way a
single enum can be used to represent match / set statements and all
variants can be rendered the same by simply printing the keys /
values.

This commit also adds a lot of new match / set statements that were
previously not supported. The crate supports now almost all match /
set statements that FRR supports - with only a few having been
omitted. Most notably it is not possible to match on community lists,
support for those is planned in a future patch series.
