This tests checks that there are no errors when receiving BFD
packets over the various linux vrf interfaces. For example, if
an incoming packet is received by the wrong socket, a VRF
mismatch error would occur, and BFD flapping would be observed.

When you have a static route with multiple different admin
distances there exists a chance that route will have been
installed multiple times due to system load when inserted
at about the same time. If this is the case then the
verify_rib function can and will select the wrong route
that happens to have a nexthop group that is still installed.
Modify verify_rib to ensure that the route that is going to
be looked at for nexthop correctness is the actual installed
route, not a previous version of it.

As of now we are logging only JSON output of CLIs
in topotests(topojson) executions and same o/p is
getting printed twice, which is of no use.
Enhanced code to show both plain and JSON output
of CLIs and remove duplicate logging.
It will help in reducing execution logs and in
verification, if sometimes there is mis-match
in CLI plain and JSON outputs.

Under heavy load I am seeing verify_rib failing after 12 seconds
but succeeding after 17:
2022-05-19 18:52:54,374 DEBUG: topolog: Exiting lib API: verify_rib
2022-05-19 18:52:54,374 DEBUG: topolog: Function returned True
2022-05-19 18:52:54,374 WARNING: topolog: RETRY DIAGNOSTIC: SUCCEED after FAILED with requested timeout of 12.0s; however, succeeded in 14.7s, investigate timeout timing
There is no reason to not have the test wait a bit longer for very very
heavily loaded systems. Change the time to 40 seconds.

Lots of tests call verify_rib that takes a list of routes that
need to be verified in some fashion. This verify_rib functionality
will try up to 12 seconds before failing the check that zebra
has the route and has installed it.
Unfortunately the verify_rib code was not looking to see if
the route was queued for installation and was then allowing
tests to immediately do subsuquent steps that depended on
that route actually being installed sometimes causing tests
to fail.
Write a bit of additional code that looks at the queued
status and allows the test to wait a bit longer for zebra
to finish processing before allowing the test to move on
to the next bit.

This test is failing intermittently because sometimes igmp
local join is not getting deleted. I did split the joins means
trying to delete igmp local joins one by one. I tried running
tests multiple times and it seems to be working fine with
current changes.
There was an issue found during debugging this test failure,
which was raised already:

a) Remove the retry mechanism to continue looking for 75%
of the time for pim code.
This alone saves a bunch of time in tests that use lib/pim.py
Effectively all the times given for retry are already long
enough. Additionally some tests are gathering data with
the expectation that they will not find data so the entire
time is being taken up in retry's. Extending the retry
mechanism makes this even worse. This is especially bad
for pim in that keep alive timers are counting down and
state can be removed due to excessive time waiting.
b) Reduce verify verify_multicast_traffic from 40 seconds
to 20 seconds to gather traffic data.
A bunch of tests are doing this:
a) gather pre test start traffic data( taking about 70
seconds to run, because a bunch of time it was looking
for data that does not exist yet)
b) run a change to introduce a different traffic flow
c) gather post test traffic data ( taking about 70
seconds to run )
Why does this matter? Tests were iterating through
all the different routers looking for traffic flow
as well as different mroute state. This is against
the keepalive timer of 210 seconds. It does not take
long before the stream can be removed and the test is
still looking for data that is no longer there due
to state timeout.
The multicast_pim_sm_topo3/test_multicast_pim_sm_topo3.py
test reduced run time from 398 seconds to 297 seconds.
Greatly reducing keepalive timeout problems.

This PR adds support for configuring topotest routers using a single file.
instead of:
```
router.load_config(
TopoRouter.RD_ZEBRA, os.path.join(CWD, "{}/zebra.conf".format(rname))
)
router.load_config(
TopoRouter.RD_OSPF, os.path.join(CWD, "{}/ospfd.conf".format(rname))
)
router.load_config(
TopoRouter.RD_BGP, os.path.join(CWD, "{}/bgpd.conf".format(rname))
)
```
you can now do:
```
router.load_frr_config(
os.path.join(CWD, "{}/frr.conf".format(rname)),
[TopoRouter.RD_ZEBRA, TopoRouter.RD_OSPF, TopoRouter.RD_BGP]
)
```
or just:
```
router.load_frr_config(os.path.join(CWD, "{}/frr.conf".format(rname)))
```
In this latter case, the daemons list will be inferred from frr.conf file.
