In a standard node update, the desired and current node config versions are represented in the `machineconfiguration.openshift.io/desiredConfig` and `machineconfiguration.openshift.io/currentConfig` node annotation values. With the introduction of OnClusterLaying (OCL), two node annotations, `machineconfiguration.openshift.io/currentImage` and `machineconfiguration.openshift.io/desiredImage`, were added to represent the desired and current image states of a node. This spike aims to help us understand if the image states should be represented in the MachineConfigNode (MCN) resource and, if so, where.

Done when:

• There is an understanding on whether we want to include image state information in the MCN resource and, if so, where it should live.
  • This decision should be documented.
• The description for MCO-1675 is updated with information on the API updates needed as a result of this investigation work.
