qos-sai: leaves the DUT with missing configs.

test_qos_sai.py is leaving the DUT with a bunch of config that was not present at the beginning of the script. After the script comes out, we see a lot of difference between golden config and the saved configs: root@xx-37-lc0:/home/cisco# diff /etc/sonic/config_db0.json /etc/sonic/running_golden_config0.json | wc 803 2077 25781 root@xx-37-lc0:/home/cisco#

root@xx-37-lc0:/home/cisco# diff /etc/sonic/config_db1.json /etc/sonic/running_golden_config1.json | wc 632 1614 20457 root@xx-37-lc0:/home/cisco#

Another issue I notice is that the BGP neighbor address for some interfaces is not present after the setup:

root@xx-37-lc0:/home/cisco# show ip int
