Feature Overview (aka. Goal Summary)  

As a cluster-admin I wish to see the status of update and see progress of update on each components.

Background
A common update improvements requested from customer interactions on Update experience is status command

1. oc update status ?
   From the UI we can see the progress of the update. From oc cli we can see this from "oc get cvo"  
    But the ask is to show more details in a human-readable format.
   Know where the update has stopped. Consider adding at what run level it has stopped.
    

   oc get clusterversion
   NAME      VERSION   AVAILABLE   PROGRESSING   SINCE   STATUS
   
   version   4.12.0    True        True          16s     Working towards 4.12.4: 9 of 829 done (1% complete)

Documentation Considerations

Update docs for UX and CLI changes
