service interfaces need to be configured correctly

DM should configure left service interface static route on private-network-nat-vrf,
and right-service-interface static route on public-network-vrf.
Currently, DM configures lefa and rightt service-interfaces on nat-vrf.

A firewall filter need to be created and applied to private vrf irb interface for
traffic to go from private vrf to natted-vrf.

for l2evpn, router-id configuration is must. Added.

both l2 & l3 need to have import export targets as policies,
vrf-targets config not required for l2
