Description of problem:
I'm trying to produce HppNotReady alert, when editing the node selector for getting the hpp broken , we can see it is not ready but the metric doesn't catch it and report it as available and the alert not fired

Version-Release number of selected component (if applicable):
4.13

How reproducible:
100%

Steps to Reproduce:
1.oc get hostpathprovisioner hostpath-provisioner -o yaml
see under .Spec.Workload.NodeSelector the value
2.oc patch hostpathprovisioner hostpath-provisioner --type='json' -p='[{"op": "replace", "path": "/spec/workload/nodeSelector", "value": {"wrong": "wrong"}}]'
and check again that the value changed with the command from step 1
3.check that the hpp is not ready:
oc get daemonset -n openshift-cnv | grep -e hostpath -e hpp
4.wait for the alert

Actual results:
The alert is not firing and the metric show hpp available

Expected results:
HppNotReady should fire
