This add support for a new controller plugin "bgp",
to manage specific bgp section by host.
This is allowing ebgp

(I'll send doc soon)

Also some fixes on pending parser

Changelog V2:

- fix some bug in bgp plugin

Alexandre Derumier (4):
  controllers: improve bgp-evpn
  zones: evpn : add support for loopback
  update test documentation
  sdn: fix : pending parser

applied, thanks!

FYI, I tried to create a somewhat sensible perlcritic config which could be useful.

It shows a few conditionally declared variables (`my $foo = 1 if $bar`) in pve-network,
among other things:

https://pve.proxmox.com/wiki/Perl_Style_Guide#Basic_Linting_with_perlcritic

Maybe it help you (and naturally all others) to avoid a few such possible bugs.
Note, it is not a complete check, e.g., it does not cares a bout a few things
(missing variables or so).
