CVO log file

Description of problem:

In a fresh installed cluster, we can see hot-loopings on Service openshift-monitoring/cluster-monitoring-operator.

# grep -o 'Updating .*due to diff' cvo2.log | sort | uniq -c 
     18 Updating CronJob openshift-operator-lifecycle-manager/collect-profiles due to diff
     12 Updating Service openshift-monitoring/cluster-monitoring-operator due to diff

Looking at the CronJob hot-looping

Version-Release number of the following components:
4.10.0-0.nightly-2022-01-09-195852

How reproducible:
1/1

Steps to Reproduce:
1.Install a 4.10 cluster
2. Grep 'Updating .*due to diff' in the cvo log to check hot-loopings
3.

Actual results:
CVO hotloops on CronJob openshift-operator-lifecycle-manager/collect-profiles

Expected results:
CVO should not hotloop on it in a fresh installed cluster
