Description of problem:
When running node-density on a 120 node cluster, we see some spikes in pod
ready latency times. These spikes correspond to a southbound DB compaction. During this compaction time the ovn-controller is not able to connect to a leader.

Version-Release number of selected component (if applicable):
4.11.0-0.nightly-2022-03-20-160505

How reproducible:
Always

Steps to Reproduce:
1. Run node-density-light on a 120 node vluster

Actual results:
Pod ready latency spikes which cause the P99 to go up

Expected results:
A steady pod ready latency during the test
