Section Number and Name: 
Applying Configuration Changes

Describe the issue: 
When enabling Azure Cloud provider by following the document [1], node role is removed. To ensure the proper scheduling, a manual step is required.

Suggestions for improvement: 
Add the following command to the document.

$ oc label node <master_node_name> node-role.kubernetes.io/master=true
$ oc label node <node_name> node-role.kubernetes.io/compute=true


Additional information: 

We can see the node role before enabling Azure Cloud provider.
$ oc describe node <node_name>
Name:               <node_name>
Roles:              master
Labels:             beta.kubernetes.io/arch=amd64
...

After restarting the node service to enable Azure cloud provider [2], Roles is none.

$ oc describe node <node_name>
Name:               <node_name>
Roles:              <none>

Since some buildconfigs or deploymentconfigs depends on this label, we have to recover the label manually.
