Enabling logging is useful to track what the code is doing.
There are some functional changes:
- The pod handler checks for existence of claims. This
avoids adding pods to the work queue in more cases
when nothing needs to be done, at the cost of
making the event handlers a bit slower. This will become
more important when adding more work to the controller
- The handler for deleted ResourceClaim did not check for
cache.DeletedFinalStateUnknown.
