There is support to configure graceful restart timer. This is the
time to wait to delete stale routes before a BGP open message is
received.
bgp graceful-restart restart-time <1-3600>
no bgp graceful-restart [<1-255>]
* bgpd/bgp_vty.c
* Define command strings for above CLI
* bgpd/bgpd.c
* bgp_config_write(): Output graceful restart-time configuration
