There are two minor changes in this PR: * Adjust quagga's jinja template to enable bgp-gr functionality by default. Currently is only applicable to those devices tagged as TOR/T0. * Ensure that no bgp-notification is sent out to remote-peers during bgpd shutdown events. The goal here is to make sure that remote-peers kick off bgp-gr-helper logic (i.e. retain restarting-router state), which can be only achieved if an ungraceful-shutdown (tcp pipe/socket down) is perceived. There are other approaches to accomplish this goal, such as draft-ietf-idr-bgp-gr-notification, but this one hasn't been implemented yet by Quagga/FRR. Signed-off-by: Rodny Molina <[email protected]>

To enforce this behavior i'm adjusting supervisord.conf to generate a SIGKILL signal during bgpd shutdown events.
