Currently, when multiple exit-nodes are defined, each exit-nodes exchanges
their own default route, so traffic is looping between both exit nodes
instead going out.
This add a new route-map to filter received type-5 on exit node

frr reload is not 100% perfect, and sometime is not able to
apply correctly changes.
Use restart in this case to be sure to have the correct config.

evpn route distinguisher is compute from bgp router-id.
if not defined, it take random ip or 0.0.0.0 and could result collisions between hosts

exitnodes-primary option force traffic to a primary node
A route-map is used to increase metric on backup nodes.
This can be usefull for snat or avoid asymetric routing.
Route-map is rework to handle multiple sequences of route map.

can be usefull if we want to join other loopback ips,
like a ceph cluster in the underlay network

This option allow an exit-node to reach itself a guest in evpn network.
Forum user have requested it, the exitnode need to reach virtual dns server in evpn.
This use a veth-pair instead a simple leak.
It's not enable by default is slowing down a little bit the routing.

allow to advertise type5 routes for evpn subnets, if vms are silents hosts.
(don't do any traffic, so anycast gateway don't have their mac-ip)

vtysh is not enough to cleanly reload configuration
This require frr-pythontools package
Also add default global values or frr-reload will try to remove them
each time
