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.

The test is failing because it assumes a json key
is always present when it is not. Test for it
before having the test fail.

I have a local test run where the sharp route-map usage
was being checked for 5 seconds. I saw usages going up
for each 1 second check and the 5th one was at 497 out
of 500. Looks like the system was really loaded. Let's
give it more time to coalesce under heavy load.

There are parts of our daemons that upon certain types
of errors that a zlog_backtrace is auto-generated.
It is desirable for this to be caught and have the
test auto-failed.

The bgp_vpnv6_per_nexthop_label tests only check to see if the mpls labels
are installed one time. Test runs show that all but one label is installed.
More than likely the test has asked for data while zebra is still installing
it. the mpls_label_check functions must check this result multiple times as
that system may be under heavy load.
A loop is introduced in order to let zebra check the mpls table.

Check `show ip route` for specific kernel routes after
the interface as their nexthop changes vrf.
After moving interface's vrf, there should be no kernel
route in old vrf.

There is no route-map set action to replace any ASN,
or a part of an ASN, with a configured ASN.
The current commit adds a new command to use a configured
ASN as replacement, instead of using the local as number.
> set as-path replace any 65500
Update the 'bgp_set_aspath_replace' test.

This test has several issues:
A) The convergence function is spamming the show neighbor command until success,
if the neighbor never comes up the test will never finish. This adds unnecessary
load to an already loaded test system. Use run_and_expect to properly wait for
the neighbor relationship to come up.
B) The convergence function should not sleep for 1 second *After* the neighbor
is established
C) The _bgp_as_path() function fails if the prefix has not been received yet.
This looking for the prefix data should be within a run_and_expect() functionality.
Else a loaded test system will fail in this function because while we may be in
an established state, prefixes might not yet have been exchanged and there is no
point in failing the test without giving the system some time to actually converge.
Fix those points, similarly to what has been fixed in
bgp_local_as_private_remove test.

It is not possible to flush all the incoming as-path list
from a given BGP update.
Add a route-map set command to remove all as-paths
from a given AS path. Add the necessary tests.

Move away from things like "lock if not locked" type code, require the
user has locked prior to geting to that point.
For now we warn if we are taking a lock we already had; however, this
should really be a failure point.
New requirements:
SETCFG -
not implicit commit - requires user has locked candidate DS and they
must unlock after
implicit commit - requires user has locked candidate and running DS
both locks will be unlocked on reply to the SETCFG
COMMITCFG -
requires user has locked candidate and running DS and they must unlock
after
rollback - this code now get both locks and then does an unlock and
early return thing on the adapter side. It needs to be un-special
cased in follow up work that would also include tests for this
functionality.

This setup demonstrates the redistribution and the proper
switching operations in an asbr device.
The setup interconnects an internal AS with an external
connected AS.
- the iBGP AS uses BGP-LU as MPLS transport
- the eBGP peering is directly connected and does use the
'mpls bgp forwarding' configuration to accept exterior
updates.
The setup performs the following tests:
- it checks for end to end connectivity from one interior
host h1 to two external hosts h2, and h3.
- it checks that the proper label values are advertised
by the ASBR to the iBGP peer, and the eBGP peer.
- it checks that the 'show mpls table' has additional
MPLS entries that permit transit mpls traffic to transit
across the ASBR. That behaviour is possible with the
'mpls bgp allocate-label-on-nexthop-change' command.
- it checks that withdraw of routes will remve the MPLS
entries.
- it checks that by unconfiguring the 'next-hop-self' option,
the external routes advertised to the internal maintain the
next-hop.
- it checks that a second prefix advertised by r3 with the
same RD, but different label value is using a new label on r2,
and that this new label value is used.
- it checks that when filtering out prefixes from r1, on r2,
then the MPLS label is deallocated, and the MPLS entry is not
present.
