Partial-Bug: 1464016 Add bgp routes with unique RDs for all bgp peers

1. Each BGP peer sends its own route : n_peers_
2. Each Agent sends its own route per instance: nagents * ninstances
3. Per agent route, one route is injected by 1/2 bgp peers with same rd
: nagents * ninstances
4. Per agent route, one route is injected by 1/2 bgp peers with different rds
: nagents * ninstances * n_peers_/2

Sum: n_peers_ + nagents * ninstances * (1 + 1 + n_peers_/2)
Expected: nroutes * (n_peers_ + nagents * ninstances * (2 + n_peers_/2))

For inet6, for part 1, half peers ended up with the same rd, thus causing the
table to have only n_peers_/2 bgp routes. This same/different rd applies only
to part 3 and 4.
