Bug Description

LLGR is currently supported in Contrail.

However, in many cases BGP routers will send NOTIFICATION messages to handle error conditions, which will make the LLGR/BGP persistence strategies inoperative.

This LP is created to track the implementation of Notification message support for GR on Contrail.
as per https://tools.ietf.org/html/draft-ietf-idr-bgp-gr-notification-10.

Add BGP Notification Flag support in GR

https://tools.ietf.org/html/draft-ietf-idr-bgp-gr-notification-10

Attempt GR Helper mode for all received notifications (and hold-timer expiry)
except HardReset and PeerDeconfigured.

Always send Notifications. NotificationFlag support has been in JUNOS already
for a while. Older versions of control-node already skips most of the
notifications received (and triggers GR helper mode)

Also fix a couple of nits found by cpplint
