When deleting a PVC fails, the following messages are repeated until a
timeout is hit:
cephfs-80811 in state &PersistentVolumeClaimStatus{Phase:,AccessModes:[],Capacity:ResourceList{},Conditions:[]PersistentVolumeClaimCondition{},} to be deleted (600 seconds elapsed)
Because the Phase is not set, the PVC seems to be in a strange state. In
case this happens, log all details from the PVC so that we can identify
additional conditions to check for completed deletion.
