MCD will send an alert when a node failes to pivot to another MachineConfig. This could prevent an OS upgrade from succeeding. The alert contains the information on what logs to look for

The alerts describes the following 

"Error detected in pivot logs on {{ $labels.node }} , upgrade may be blocked. For more details:  oc logs -f -n {{ $labels.namespace }} {{ $labels.pod }} -c machine-config-daemon "

It is possible that admin may not be able to interpret exact action to be taken after looking at MCD pod logs. Adding runbook (https://github.com/openshift/runbooks) can help admin in better troubleshooting and taking appropriate action.

Acceptance Criteria:

• Runbook doc is created for MCDPivotError alert
• Created runbook link is accessible to cluster admin with MCDPivotError alert
