The MCO was getting a lot of requests pertaining to what updating, updated, and degraded meant as well as how to identify a "problem node" easily. As a result of MCO-463, the proposed solution is to expose node states in `oc get mcp` in the a format similar to the following:

`DegradedNodes

node.1.2.3: reason

UpdatingNodes

node.4.5.6: reason

UnavailableNodes

node.7.8.9: reason`

This format (or something like this) will allow users to easily identify and act on a node that is in an undesirable or unfamiliar state. So, the work here is to modify the existing machineconfigpool crd to give users more verbose output and to adapt the existing status logic to provide this data.
