Build Update for numansiddique/ovn
-------------------------------------

Build: #85
Status: Failed

Duration: 16 mins and 3 secs
Commit: 72f1a18 (controller_heartbeat/v1)
Author: Numan Siddique
Message: Add chassis liveliness support

Presently there is no way for CMS to know if ovn-controller running in a chassis
is down or not. In the case of OpenStack, networking_ovn makes use of
nb_cfg/hv_cfg columns of NB DB's NB_Global table. Every few seconds, networking-ovn
increments nb_cfg's value and expects all the ovn-controller's update nb_cfg column
in Chassis table of SB DB. In a large deployment (with 1000 nodes) this approach
is causing SB ovsdb-server to consume 100% CPU all the time.

This patch adds a native liveliness support in OVN so that all the CMS can benefit
from it. Since ovn-controller's don't monitor the Chassis table, ovsdb-server
will not send update notifications to all the ovn-controllers. This would save
lot of CPU cycles.
