With the API changes made in MCO-1675, new properties were added in the MachineConfigNode (MCN) Spec and Status to hold the values of the `machineconfiguration.openshift.io/desiredImage` and `machineconfiguration.openshift.io/currentImage` node annotations. This test should ensure that the MCN properties, both new and pre-existing, are set as expected when on cluster image mode is enabled and disabled.

This test will be similar to the test created in MCO-1595. However, it needs to validate the new MCN properties added in MCO-1675 both when on-cluster image mode is enabled on a node and when it is not.

At a high-level, the sequence of this test will likely be something like:

1. Validate starting properties of the MCN.
2. Create a custom MachineConfigPool (MCP) & add a node to it.
3. Validate the properties of the MCN.
4. Enable on cluster image mode by applying a MachineOSConfig.
5. Validate the properties of the MCN.
6. Disable on cluster image mode by deleting the applied MachineOSConfig.
7. Validate the properties of the MCN.

Done when:

• Test exists for the ImageModeStatusReporting feature gate to validate that MCN properties are correctly populated when on-cluster image mode is enabled on a node and when it is not in openshift/machine-config-operator/test/extended

Depends on:

• This test will probably need to be tagged as `Disruptive` since it will result in node reboots. Thus, completing this story depends on the MCO team having a test suite where running disruptive tests is allowed (see MCO-1679 & MCO-1652).
• Creating this test will be much simpler and straightforward once the framework for on-cluster image mode tests in the MCO is established (see MCO-1609).
• These tests should contribute to the StatusReporting feature gate’s component readiness score. Therefore, this test should be created after the StatusReporting feature gate exists (see MCO-1681).
• This test depends on on-cluster image mode tests statuses existing in the MCN API & the associated functionality being implemented in the MCO (see MCO-1675, and MCO-1713).
