Add a new topotest for getting the aigp from the "igp-metric"
for a redistributed route (ospf route in the test).

Fix and adjust the topotest post the fix for route selection with
AIGP.
When there are multiple IGP domains (OSPF in this case), the nexthop
for a BGP route with the AIGP attribute must be resolved in its own
IGP domain.
The changes in r2/bgpd.conf and r3/bgpd.conf are needed as incorrect
IGP metrics are received from NHT for the recursive nexthops. Once
the issue is resolved, the changes can be reverted.

This test was killing bgp on r1 and r2
and then immediately testing that the
default route transitioned. Unfortunately
the test was written that under load the
system might be in a bad state. Let's
modify the code to check for a bgp version
change and then that the bgp state has
come back up

After setting down nhs1, the test is checking that nhc1 routing table
matches routes in nhc1/nhrp_route.json. It is incorrect because it
checks that the NHRP route to nhs1 is still present but it should have
disappeared.

The expected prefix should be 5.5.5.0/24 otherwise the hosts behind NHRP
client 1 nhc1 (aka. r5) are not reachable via NHRP.
The issue was not seen in the FRR official CI because the tests were
skipped because iptables were missing in CI machines.
It solves the 16690 issue.

(cherry picked from commit 5a70378a47)
Current code when a link is set down is to just mark the
nexthop group as not properly setup. Leaving situations
where when an interface goes down and show output is
entered we see incorrect state. This is true for anything
that would be checking those flags at that point in time.
Modify the interface down nexthop group code to notice the
nexthops appropriately ( and I mean set the appropriate flags )
and to allow a `show ip route` command to actually display
what is going on with the nexthops.

(cherry picked from commit 0df2e14997)
The isis_tilfa_topo1 topotest is comprehensive and contains a large
amount of reference data. One problem is that, when changes occur,
updating this reference data can be difficult.
To address this problem, this commit introduces a method to
automatically regenerate the reference data by setting the `REGEN_DATA`
environment variable.
Usage:
$ REGEN_DATA=true python3 ./test_isis_tilfa_topo1.py
When `REGEN_DATA` is set, the topotest regenerates reference data
from the current run instead of comparing against existing reference
data. Note that regenerated data must be manually verified for
correctness.
This commit also simplifies the reference data by replacing all diff
files with complete JSON snapshots.

In this topotest, steps 10-15 were added to test the IS-IS switchover
functionality. In short, two cases were tested: switchover after a
link down event and switchover after a BFD down event. Both cases
were tested in sequence on the same router, rt6. This involved the
following steps:
- Setting the SPF delay timer to 15 seconds
- Shutting down the eth-rt5 interface from the switch side
- Testing the post-switchover RIB and LIB (triggered by the link down
event)
- Testing the post-SPF RIB and LIB
- Bringing the eth-rt5 interface back up
- Configuring a BFD session between rt6 and rt5
- Shutting down the eth-rt5 interface from the switch side once again
- Testing the post-switchover RIB and LIB (triggered by the BFD down
event)
- Testing the post-SPF RIB and LIB
Since the time window to test the post-switchover RIB and LIB was too
narrow (10 seconds), these tests were having sporadic failures.
To resolve this problem, we can simplify the switchover test as follows:
- Setting the SPF delay timer to 60 seconds (not 15)
- Disabling "link-detect" on rt6's eth-rt5 interface
- Shutting down the eth-rt5 interface from the switch side
- On rt6, testing the post-switchover RIB and LIB (triggered by the
BFD down event)
- On rt5, testing the post-switchover RIB and LIB (triggered by the
link down event)
Notice how we can test both post-link-down and post-BFD-down switchover
cases simultaneously by having different "link-detect" configurations
on rt5 and rt6. Additionally, by using a larger SPF delay timer, the
time window to test the post-switchover RIB and LIB is much larger
and less prone to sporadic failures.

The test is done on r2. A BGP update is received on r2, and is
filtered on r2. The RIB of r2 does not have the BGP update stored,
but the ADJ-RIB-IN is yet present. To demonstrate this, if the
inbound route-map is removed, then the BGP update should be copied
from the the ADJ-RIB-IN and added to the RIB with the label
value.
