Description of problem:
We installed HPP CR with pvcTemplate based on CEPH storage class. CEPH got CriticallyFull and some hpp-pool pods couldn't create. 

Version-Release number of selected component (if applicable):
4.12, 4.11, 4.10

How reproducible:
Only when there's a problem with the underlying storage class

Steps to Reproduce:
1. Create HPP CR with pvcTemplate based on CEPH
2. Use all CEPH storage
3. Delete HPP CR

Actual results:
$ oc get pods -A | grep hpp
openshift-cnv    hpp-pool-29ab9406-85bc665cdb-wqz7j   1/1  Running  0  46h
openshift-cnv    hpp-pool-4356e54b-7ccf5c44d-95tkr    1/1  Running  0  46h
openshift-cnv    hpp-pool-7dfd761c-6ffd959c85-tfqds   0/1  ContainerCreating  0 19m

$ oc delete hostpathprovisioner hostpath-provisioner
hostpathprovisioner.hostpathprovisioner.kubevirt.io "hostpath-provisioner" deleted
(STUCK)

$ oc get jobs -n openshift-cnv 
NAME                    COMPLETIONS   DURATION   AGE
cleanup-pool-4dd1b8bf   0/1           13m        13m
cleanup-pool-d1954b6a   0/1           13m        13m
cleanup-pool-edb68ab8   1/1           6s         13m


Expected results:
HPP CR deleted


Additional info:
As a W/A: delete the cleanup pods manually, they will be recreated and they will complete successfully.
