Build Update for ovsrobot/ovn
-------------------------------------

Build: #27
Status: Passed

Duration: 1 hr, 14 mins, and 47 secs
Commit: fb746a2 (series_122036)
Author: Numan Siddique
Message: ovn-northd: Add the option to pause and resume

This patch adds 3 unixctl socket comments - pause, resume and is-paused.

Usage: ovs-appctl -t ovn-northd pause/resume/is-paused

This feature will be useful if the CMS wants to
  - deploy OVN DB servers in active/passive mode and
  - run ovn-northd on all these nodes and use unix ctl sockets to
    connect to the local OVN DB servers.

On the nodes where OVN Db ovsdb-servers are in passive mode, the local ovn-northds
will process the DB changes and compute logical flows to be thrown out later,
because write transactions are not allowed by these ovsdb-servers. It results in
unncessary CPU usage.

With these commands, CMS can pause ovn-northd on these node. A node
which becomes master, can resume the ovn-northd.

One use case is to use this feature in ovn-kubernetes with the above deployment model.
