Description of problem:
I see that cluster instance for secondary scheduler operator does not get created and when looking into the operator logs i see that there has been a panic observed.

secondaryscheduleroperator.v1.0.0   Secondary Scheduler Operator for Red Hat OpenShift   1.0.0                Succeeded


How reproducible:
Always

Steps to Reproduce:
1. Install secondary scheduler operator from operator hub
2. create secondary-scheduler-config configmap using the yaml below
apiVersion: v1
kind: ConfigMap
metadata:
  name: "secondary-scheduler-config"
  namespace: "openshift-secondary-scheduler-operator"
data:
  "config.yaml": |
    apiVersion: kubescheduler.config.k8s.io/v1beta1
    kind: KubeSchedulerConfiguration
    leaderElection:
      leaderElect: false
    profiles:
      - schedulerName: secondary-scheduler
        plugins:
          score:
            disabled:
              - name: NodeResourcesBalancedAllocation
              - name: NodeResourcesLeastAllocated

3. Now create new cluster instance for secondary scheduler by adding the image as schedulerImage: 'k8s.gcr.io/scheduler-plugins/kube-scheduler:v0.22.6'

Actual results:
cluster pod for secondary scheduler operator does not become running and checking the operator logs shows there is a panic

Expected results:
Cluster pod for secondary scheduler operator should be running and there should be no panic.
