MissingMachineConfig alert is not triggered when the MCD fails because it can find the MC
    

quay.io/openshift-release-dev/ocp-release:4.16.0-x86_64
    

Always
    

    1. Create a MC to deploy any file in the worker MCP
    
    Get the name of the new rendered MC
    
    rendered-worker-bf829671270609af06e077311a39363e 9e4a1f5f4c7ef58082021ca40556c67f99062d0a   3.4.0             23s
    
    2. When the first node starts updating, delete the new rendered MC
    
    oc delete mc rendered-worker-bf829671270609af06e077311a39363e
    
    
    

	The node is rebooted, an error regarding the missing MC is reported in the logs but no alert is fired

        This is the logs:
