* Rename asn/deployment_id_asn_map.yaml to constants/constants.yaml
* Fix bgp templates
* Add community for loopback when bgpd is isolated
* Use correct community value
Now it's possible to add and remove peers based on ConfigDB
- What I did
Fixed functionality for dynamically adding/removing static bgp peers.
- How I did it
Split the bgp default template on bgp part and bgp peer part
Changed bgpcfgd to use 1.
