Logs like the following are constantly emitted by the clustersizing controller:

  sometimes  

    1. Set up a management cluster with size tagging
    2. Create a hosted cluster
    3. Delete the hosted cluster
    

    The hypershift operator continues logging about not being able to find the deleted hosted cluster.

    No additional logging happens.

    The clusterszing controller returns an error when it can't find a hostedcluster instead of returning nil. This causes that hostedcluster to be requeued indefinitely.
