Sean Eagan e663f81ff2 Various reconciliation fixes
- Reduce log noise by logging errors instead of successes
- Use context logger provided by controller-runtime
- Patch status instead of update to avoid "the object has been modified; please apply your changes to the latest version and try again"
- Add finalizer even if object is already under deletion, in case we never got a chance yet
- Don't set RequeueAfter on errors since it is ignored anyway [0]
