Description aharchin 2022-05-16 10:36:00 UTC 
Description of problem: 

After upgrading OCS cluster from 4.8 to ODF 4.9 multiple duplicate alerts:

While checking able to see multiple prometheus rules:

~~~
#  oc get prometheusrule -n openshift-storage
NAME                        AGE
noobaa-prometheus-rules     152d
ocs-prometheus-rules        152d
prometheus-ceph-v14-rules   152d
prometheus-ceph-v16-rules   89d
~~~


Rule `prometheus-ceph-v14-rules` and `prometheus-ceph-v16-rules` are having almost same alerts. Which seems to be the cause of duplicate alerts.


After deleting `prometheus-ceph-v14-rules` duplicate alerts vanished and operator did not reconcile the prometheus rule again.

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

After upgrading OCS cluster from 4.8 to ODF 4.9 

Actual results: Duplicate alerts


Expected results: Operator should delete the old prometheusrule `prometheus-ceph-v14-rules`.



Additional info: Attaching cluster and storage mustgather for reference.
