This card extend the CI coverage for the new rule that got accepted recently.

A component in a cluster with less than 250 nodes must complete a version change within a limited period of time: 90 minutes for Machine Config Operator and 20 minutes for others.

DoD:

• An test existing in o/origin that covers the above rule.
• (After soaking 1week?) Open bugs for the COs that violates the rule and add them as exceptions for the test.

For grooming:

An idea for implementation is to check Failing=Unknown in the condition of ClusterVersion's condition. Currently, it is close to the above rule, with the difference of limit=30m (instead of 20m). We may tighten it to 20m in CVO's code if realistic.
