This log ignore causes one of the tests that are expected to fail in the CI check to pass, will be moving this logignore to manual extend in the individual test files with loganalyzer[dutIndex].ignore_regex.extend

Will involve:
snmp/test_snmp_queue_counters.py
drop_packets/drop_packets.py
bgp/test_bgp_bbr_default_state.py
bgp/test_bgp_bbr.py
