Fixed TSA bugs:
1. TSA didn't advertise Loopback ipv6 address
2. TSA and TSB changed BGP dynamic and BGP monitors sessions
**- How to verify it**
Build an image and run on your DUT.
```
admin@str-s6100-acs-1:~$ TSA

admin@str-s6100-acs-1:~$ vtysh -c 'show bgp ipv4 neighbors 10.0.0.1 advertised-routes'
