With the API updates made in MCO-1675, two new conditions, namely `MachineConfigNodeUpdateOS` and `MachineConfigNodeUpdateFiles`, were introduced to replace the previously existing `MachineConfigNodeUpdateFilesAndOS` condition. This story involves making the necessary MCO code changes to divide the singular condition into the two more specific conditions. It also includes making necessary changes to the MachineConfigNode (MCN) and Image Mode Status Reporting regression tests so that they reflect the implementation updates.

Done when:

• `MachineConfigNodeUpdateOS` and `MachineConfigNodeUpdateFiles` have been introduced into the MCN conditions in the MCN flow
• `MachineConfigNodeUpdateFilesAndOS` is no longer being used
• Regression tests have been updated to reflect the condition updates
