topotests: add bgp_nhg_zapi_scalability ebgp test
Add a test similar to bgp_nhg_zapi_scalability ibgp test, except that a route server is put in place in r3 insted of a route reflector. ebgp configuration is done so that ebgp multihop is accepted and as paths list is ignored. In that way, ECMP paths are visible. It is however not possible to have ECMP paths with 2 different ebgp peers, as neighbor IP comparison will be applied. So a part of the test is removed.
