Current isis tests use a variety of hello timers as well
as hello-multiplier, let's modify all of the isis test
cases to use 1 and 10. This cleans up some spurious test
failures I was seeing locally. As an example without
these changes running isis_tilfa_topo1 2r6 times I would
see 5-10 test failures now I am seeing ~2 test failures.
In any event part of the problem was that some tests were
not fully converged when looking at them under heavy
system load. Changing this to 1/10 gives us 10 chances
to see the incoming packet.

Starting from step 11, this topotest focuses on validating the TI-LFA
switchover functionality, where the backup nexthops are activated
after an adjacency expires, either with or without BFD.
Currently, the test checks the RIB shortly after the switchover using
a tight 5 seconds interval to ensure that the RIB update is due to the
switchover and not an SPF update (which is configured with an initial
delay of 15 seconds). However, it was observed that the kernel might
take longer than 5 seconds to install routes when the system is under
heavy load. To account for that, double the wait interval so that
this topotest will succeed even in those conditions.

In this topotest, BFD is configured at the end of step 13. However,
in certain cases where the testing machine is exceptionally fast (e.g.,
Donald's quantum computer), there is a possibility that the interface
shutdown event from step 14 may occur before BFD has had sufficient
time to establish the session, which leads to a test failure. To fix
this problem, ensure the BFD session is up before proceeding to the
next step.

In this topotest, the IS-IS hello interval is set to 1 for fast
convergence. However, the current hello multiplier of 3 results in a
tight IS-IS adjacency holdtime of 3 seconds. This tight timeframe can
cause failures when the testing machine is running multiple tests at
full capacity. To improve stability under such conditions, this commit
raises the hello multiplier to 10, providing a more forgiving holdtime
and reducing the likelihood of failures.

The isis_tilfa_topo1 test is failing because insufficient time was
given for isis to converge on the system under system load. Extend
the time and decrease the hello-interval timers to give it more
of a chance to converge.

Ensure that the minimum time spent run and expecting is
5 seconds. Heavy load is not a reason to fail a test.

Add a switchover test that consists in clearing the rt2 neighbor on rt1.
Check that the switchover between primary and backup happens before the
SPF re-computation.

Add a switchover test that consists in:
- Setting up ISIS BFD between rt5 and rt6
- Setting no link-detect on rt6 eth-rt5 so that zebra does not take
account linkdown events on this interface.
- Shutting down rt6 eth-rt5 from the switch side
Check that the switchover between primary and backup happens before the
SPF re-computation.

When Segment Routing is disabled, if isisd received LSP with Segment Routing
information, in particular prefix SIDs, it installs corresponding MPLS entries
while it should not as SR is disabled.
This patch adds extra control to verify if SR is enabled or not before
configuring MPLS LFIB & IP FIB with prefix SIDs and adjust SR & TI-LFA
tests accordingly.

Debugs take up a significant amount of cpu time as well as
increased disk space for storage of results. Reduce test
over head by removing the debugs, Hopefully this helps
alleviate some of the overloading that we are seeing in
our CI systems.

Change every `-` to `_` in directory names. This is to avoid mixing _ and -.
Just for consistency and directory sorting properly.
