Description of problem:
As described in: https://github.com/metal3-io/baremetal-operator/pull/565

The code to write the 'status' annotation (an annotation containing the Status data) whenever the status changes can cause an infinite hot loop. Since the annotation and the Status subresource cannot be written at the same time, we re-read the object after writing the annotation and before trying to write the Status. However, if we get a previously cached version then there will be an error and we'll begin the Reconcile cycle again. The new Status changes generated by this new Reconcile may contain different timestamps, which will result in the annotation being updated and the whole cycle repeating. Rate limiting helps to ensure that once this happens once the timestamps only get further and further apart, so the loop is self-sustaining.

We don't actually need or want to write a status annotation. We want to be able to *read* one, and we backported the code to do so to both 4.5 (bug 1835457) and 4.4 (bug 1843230). However, the code to both read and create the annotation was in the same patch, so we ended up with both.
