In test_bgp_mutli_vrf_topo2.py it's clear that we remove then
re-add the vrf interfaces. Then the test was immediately
checking to ensure that the routes were available.
BGP needs time to reconverge. Let's ensure that first.

The test_bgp_multi_vrf_topo2.py script had a bunch
of places where it would change an interface status
or add delete routes that would affect bgp convergence
but it was never ensuring that convergence had happened
before the test verified the bgp rib. I believe this
was leading to many intermittant ci failures in
testing for other PR's to be accepted. Modify
the code to wait for bgp convergence if we just
made a change to the topology

1. Added linux kernel version check to avoid failures
in CI systems if matching kernel version not found.
