[Bug]: A lot of new reconciles are triggered as objects are changed frequently by the controller

[gvdhart]

What happened

There are a lot of new reconciles triggered as the controller itself edits the k8s objects frequently (Spec and Status, this is normal k8s controller reconciler behavior).
Therefore reconciles really need to be idempotent otherwise there are a lot of issues.

Step to reproduce

Deploy an OscMachine and check the logs

Expected to happen

We should limit the number of updates the controller does on the kubernetes object.
Or we should really make sure that all reconcile loops are idempotent.
