Action required

Since update logic has been moved to operator, PodManagementPolicy has been set to Parallel in redis statefulSet. This improve bootstrap times. This field is immutable so to upgrade from previous rc releases you need to delete statefulSets manually. Note: you can use --cascade=false flag to avoid disruption, pods will be adopted by the new statefulSet created by the operator. example: kubectl delete statefulset --cascade=false rfr-redisfailover
