I cleaned a lot of stuff up in the frr plugin.
I tested it all in my own test environment, but if somebody who also uses BGP/OSPF/OSPFv3 peering and has some basic development knowledge (aka how to build an opnsense plugin from master, deploy it, and report issues) it would be nice to get some feedback before pushing this out.
Please, test it if you can, its a lot of changes but less so feature wise, mostly corrections.

Check out the 2.0 changelog and the migration notes (there are a few migrations happening automatically).
Thank you for any help (and if not brace for impact on community at some point regardless :D)
