Add control plane update status to "oc adm upgrade status" command output.

Note: In future we want to add  "Est Time Remaining: 35m" to this output but need a separate card.

Sample output :

=Control Plane =
Assessment: Progressing - Healthy
Completion: 45%
Duration: 23m
Operator Status: 33 Total, 33 Available, 4 Progressing, 0 Degraded

Todo:

• Add code to get similar output
• If this needs a significant code change, please create new Jira cards.
