[R2.2 46] BGP Peering doesn't happen when ibgp_auto_mesh is enabled.

[asbalaji]

BGP Peering doesn't happen when ibgp_auto_mesh is enabled.

Schema generator is not setting bgp router refs for all control nodes.

Sanity is explicitly setting bgp router refs for all provisioned control nodes (provision_bgp) so the issue is not seen in sanity.

Peering happens when we disable this flag and explicitly setting peers. Observed this behaviour in both UI and REST API calls.

Also, the 'autonomous_system' tag in 'global-system-config' is seen as a string (should be an integer as per schema) in 'defaults' (provision_control.py) when system comes up initially.
 defaults = {
            'router_asn': '64512',
            'ibgp_auto_mesh': None,
            'api_server_ip': '127.0.0.1',
            'api_server_port': '8082',
            'oper': None,
            'admin_user': None,
            'admin_password': None,
            'admin_tenant_name': None
        }

Fix multiple issues with ibgp auto mesh

1. vendor name was not being initialized
2. router asn change and global asn change need to be handled differently
3. create peering among all routers with asn same as global
