The clusterlogging CR can't be removed, and below is the finalizers in the clusterlogging CR:

    finalizers:

Steps to Reproduce:

1. deploy logging 5.6 or 5.7.1, and use lokistack as the default log store
2. upgrade logging to 5.7.2, and wait for all the logging components to be upgraded
3. try to remove clusterlogging CR
4. check pod status

Actual results:
