This change alters the behavior of existing test code. The
default mode (before any call to luSetWaitType()) is now
"strict".
The historical behavior of luCommand(op="wait) is to ignore
failures to match the specified regexp in the specified time.
In those cases, no result was logged and no error was signaled.
This change introduces a new "strict" mode for luCommand(op="wait):
in "strict" wait mode, each invocation of luCommand(op="wait)
generates an explicit, logged failure result when it fails to match
the specified regexp in the specified time. These failures signal
an error for the test.
Calling luSetWaitType("nostrict") restores the historical behavior.
Calling luSetWaitType("strict") (re)enables the new strict behavior.
Individual calls to luCommand() may also specify op="wait-nostrict"
to override any default and use the historical behavior.
Individual calls to luCommand() may also specify op="wait-strict"
to override any default and use the new behavior.

Test that BFD static monitoring works:
When BFD session is up the routes are installed in the RIB and
distributed with routing protocol (in this case BGP). When the session
is down it is removed from RIB and propagated.

Previously, routes leaked from one VRF to another VRF were associated
with the original nexthop interface.
Commit 14aabc0156 replaced the nexthop
interface with the index of incoming VRF interface.
Due to this change, the `bgp_srv6l3vpn_route_leak` topotest always fails
because it still expects the nexthop interface.

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`.

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 ).
