The `bgp_srv6l3vpn_to_bgp_vrf2` topotest tests the SRv6 IPv4 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.
Currently, the `bgp send-extra-data zebra` option is not set in the
`bgpd` configuration, which always causes the topotest to fail.
This commit fixes the `bgp_srv6l3vpn_to_bgp_vrf2` topotest by enabling
the `bgp send-extra-data zebra` option for both routers `r1` and `r2`.

isis_lfa_topo1 topotests regularly fails at step 24. The test expects
that the BFD session between rt1 and rt2 comes down after shutting the
link between rt1 and rt2.
Since the BFD is multihop, the BFD can get back through rt3.
Set the BFD type to single-hop.

We already have a global knob for graceful-shutdown, but it's handy having
per neighbor knob as well.
Especially when a single neighbor needs to be restarted/shutdown gracefuly.
We can do this route-maps, but this is a faster/cleaner way doing the same
for an operator.

This test ensures that the command `behavior usid` works properly.
When the `behavior usid` command is set, a flag is added to the locator
to indicate that the locator is a uSID locator. This test verifies that
the locator works correctly when you set / unset the `behavior usid`
command.

When zebra receives routes from upper level protocols it decodes the
zapi message and places the routes on the metaQ for processing. Suppose
we have a route A that is already installed by some routing protocol.
And there is a route B that has a nexthop that will be recursively
resolved through A. Imagine if a route replace operation for A is
going to happen from an upper level protocol at about the same time
the route B is going to be installed into zebra. If these routes
are received, and decoded, at about the same time there exists a
chance that the metaQ will contain both of them at the same time.
If the order of installation is [ B, A ]. B will be resolved
correctly through A and installed, A will be processed and
re-installed into the FIB. If the nexthops have changed for
A then the owner of B should be notified about the change( and B
can do the correct action here and decide to withdraw or re-install ).
Now imagine if the order of routes received for processing on the
metaQ is [ A, B ]. A will be received, processed and sent to the
dataplane for reinstall. B will then be pulled off the metaQ and
fail the install since A is in a `not Installed` state.
Let's loosen the restriction in nexthop resolution for B such
that if the route we are dependent on is a route replace operation
allow the resolution to suceed. This requires zebra to track a new
route state( ROUTE_ENTRY_ROUTE_REPLACING ) that can be looked at
during nexthop resolution. I believe this is ok because A is
a route replace operation, which could result in this:
-route install failed, in which case B should be nht'ing and
will receive the nht failure and the upper level protocol should
remove B.
-route install succeeded, no nexthop changes. In this case
allowing the resolution for B is ok, NHT will not notify the upper
level protocol so no action is needed.
-route install succeeded, nexthops changes. In this case
allowing the resolution for B is ok, NHT will notify the upper
level protocol and it can decide to reinstall B or not based
upon it's own algorithm.
This set of events was found by the bgp_distance_change topotest(s).
Effectively the tests were looking for the bug ( A, B order in the metaQ )
as the `correct` state. When under very heavy load, the A, B ordering
caused A to just be installed and fully resolved in the dataplane before
B is gotten to( which is entirely possible ).

Column headers in BGP routes table are not aligned with data when
RPKI status is available. This was fixed to insert a space at the
beginning of the header and at the beginning of lines that do not
have RPKI status.
This fix requires that several testing templates be adjusted to
match the new output.

Add a switchover test that consists in:
- Setting up ISIS BFD between rt1 and rt2
- The no link-detect setting on rt1 eth-rt2 is still present so that
zebra does not take account linkdown events on this interface.
- Shutting down rt1 eth-rt2 from the switch side
- Wait for BFD to comes down
Check that the switchover between primary and backup happens before the
SPF re-computation.
