[OVN] Enable ovn-monitor-all to help with OVN scale

[Kamil Sambor]

Description of problem:

With conditional monitoring enabled in OVN, southbound ovsdb-server takes lot of time in handling the monitoring and sending the updates to all its connected clients. Its takes lot of CPU.

With monitor-all option, all ovn-controllers do not enable conditional monitoring there by reducing the load on the Southbound ovsdb-server.

To enable monitor-all option, CMS/cloud operator should run the below command on each chassis

ovs-vsctl set open . external_ids:ovn-monitor-all=true

Version-Release number of selected component (if applicable):
