this ifindex is not guaranteed to be any particular value by the underlying

The `bgp_srv6l3vpn_to_bgp_vrf3` topotest tests the SRv6 L3VPN
functionality. It applies the appropriate configuration in `bgpd` and
`zebra`, and then checks that the RIB is updated correctly.
The topotest expects to find the AS-Path in the RIB, which is only
present if the `bgp send-extra-data zebra` option is enabled in the
`bgpd` configuration.
The `bgp send-extra-data zebra` option has been accidentally commented
out in commit 2007e2dbd0.
This commit fixes the `bgp_srv6l3vpn_to_bgp_vrf3` topotest by re-adding
the missing `bgp send-extra-data zebra` option.

This test is setting the dead interval to 4 seconds, seeing a 6 second delay where the os has gone to town
(probably because of the high load on the system ) and not choosing the correct neighbor as the DR.
OSPF when coming up and after seeing the first neighbor, goes into a waiting period before
the DR is elected. If the neighbor does send it's hello packets but they are not processed
before the wait timer pops because of the starvation event, then the wrong neighbor
will be elected DR. Let's give this test a bit more time to decide who the
DR is in case everything goes a bit south.

The flag for telling BGP that a route is expected to be installed
first before notifying a peer was always being set upon receipt
of a path that could be accepted as bestpath. This is not correct:
imagine that you have a peer sending you a route and you have a
network statement that covers the same route. Irrelevant if the
network statement would win the flag on the dest was being set
in bgp_update. Thus you could get into a situation where
the network statement path wins but since the flag is set on
the node, it will never be announced to a peer.
Let's just move the setting of the flag into bgp_zebra_announce
and _withdraw. In _announce set the flag to TRUE when suppress-fib
is enabled. In _withdraw just always unset the flag as that a withdrawal
does not need to wait for rib removal before announcing. This will
cover the case when a network statement is added after the route has
been learned from a peer.

This test demonstrates that a label is allocated for each
ipv6 next-hop. IPv6 test introduces link local ipv6 addresses
as next hops, and compared to IPv4, one can have two different
next-hops depending if the next-hop is defined by a global
address (static route redistributed) or a bgp peer.
This test checks that:
- The labels are correctly allocated per connected next-hop.
- The default label is used for non connected prefixes.
- The withdraw operation frees the MPLS entry.
- If a recursive route is redistributed by BGP, then the nexthop
tracking will find the appropriate nexthop entry, and the
associated label will be found out.
- When a prefix moves from one peer to one another behind the
vrf, then the MPLS switching operation for return
traffic is changing the outgoing interface to use.
- When the 'label vpn export <value>' MPLS label value is changed,
then the modification is propagated to prefixes which use that value.
- Also, when unconfiguring the per-nexthop allocation mode, check
that the MPLS entries and the VPNv4 entries of r1 are changed
accordingly.
- Reversely, when re-configuring the per-nexthop allocation mode,
check that the allocation mode reuses the other label values.
