Verify it. LGTM

1. Install a 4.6.x openshift cluster with this bug fix
[root@preserve-olm-env 1924257]# oc get clusterversion
NAME      VERSION                             AVAILABLE   PROGRESSING   SINCE   STATUS
version   4.6.0-0.nightly-2021-02-04-203135   True        False         35m     Cluster version is 4.6.0-0.nightly-2021-02-04-203135
[root@preserve-olm-env 1924257]# oc adm release info registry.ci.openshift.org/ocp/release:4.6.0-0.nightly-2021-02-04-203135 --commits|grep operator-lifecycle-manager
  operator-lifecycle-manager                     https://github.com/operator-framework/operator-lifecycle-manager            9dde58210568d45cdb8dfe9b67d4f4f24458a853

2. Install Red Hat Openshift Cluster Storage (OCS) operator and Advanced Cluster Management (ACM) operator, Wait for the operator to finish installing
login openshit, click Operators -> OperatorHub, search "OpenShift Container Storage" and "Advanced Cluster Management for Kubernetes", instal them
[root@preserve-olm-env 1924257]# oc get csv -n openshift-storage 
NAME                  DISPLAY                       VERSION   REPLACES   PHASE
ocs-operator.v4.6.2   OpenShift Container Storage   4.6.2                Succeeded
[root@preserve-olm-env 1924257]# oc get csv -n open-cluster-management
NAME                                 DISPLAY                                      VERSION   REPLACES                             PHASE
advanced-cluster-management.v2.1.2   Advanced Cluster Management for Kubernetes   2.1.2     advanced-cluster-management.v2.1.0   Succeeded

3. check the OLM operator pod's logs
[root@preserve-olm-env 1924257]# oc logs --since=400s olm-operator-5cc64d7f79-m8pfs | grep -i debug | grep -i "reconciling operator"
2021-02-05T04:51:24.725Z	DEBUG	controllers.operator	reconciling operator	{"request": "/advanced-cluster-management.open-cluster-management"}

2021-02-05T04:51:36.907Z	DEBUG	controllers.operator	reconciling operator	{"request": "/ocs-operator.openshift-storage"}

[root@preserve-olm-env 1924257]# oc logs --since=300s olm-operator-5cc64d7f79-m8pfs | grep -i debug | grep -i "reconciling operator"
[root@preserve-olm-env 1924257]# 

4. Observe the CPU core usage of the OLM operator pod from the console. 
The cpu usage is back to normal after the operator installation is finished.

5. check the CSV for the operator
[root@preserve-olm-env 1924257]# oc -n openshift-storage get csv -w
NAME                  DISPLAY                       VERSION   REPLACES   PHASE
ocs-operator.v4.6.2   OpenShift Container Storage   4.6.2                Succeeded

[root@preserve-olm-env 1924257]# oc -n openshift-storage get ip
NAME            CSV                   APPROVAL    APPROVED
install-gdgmc   ocs-operator.v4.6.2   Automatic   true
[root@preserve-olm-env 1924257]#
