bgpd: Add Long-lived Graceful Restart capability (restarter)
Restart Router mode.
FRRouting (Restarter):
```
bgp long-lived-graceful-restart stale-time 10
bgp graceful-restart restart-time 1
```
Tested with GoBGP (Helper):
```
long-lived-graceful-restart: advertised and received
Local:
ipv4-unicast, restart time 100000 sec
Remote:
ipv4-unicast, restart time 10 sec, forward flag set
```
Logs:
```
