Section Number and Name: 

Describe the issue:
Updating the cluster build configuration takes time to be applied to the cluster. As a result, customers may expect certain behavior to occur right after the cluster build configuration has been applied.


Suggestions for improvement: 
Add a section to explain how customers can verify the cluster has been updated with the new configuration:

1. Watch the openshift-controller-manager ClusterOperator - this will report `Progressing=True` while the configuration is being applied.

Via oc:
```
$ oc get clusteroperator openshift-controller-manager -w
```
or in the web console.

2. Watch the controller-manager DameonSet - this will report `Updated=3` when the configuration has been applied to all openshift controller managers.

Via oc:
```
$ oc get ds controller-manager -n openshift-controller-manager -w
```
or in the web console.
