Pods are not schedulable after setting defaultNodeSelector for the Scheduler

Issue

• Pods are not schedulable after defining defaultNodeSelector and proper labels on workers

• In oc get events -n $PROJECT there are warnings for deployments like:

  Error creating deployer pod: unable to parse requirement: label value: Invalid value: "''": must match format [ DNS 1123 subdomain / ] DNS 1123 label
  

  or

  Error creating: unable to parse requirement: label value: Invalid value: "\"\"": must match format [ DNS 1123 subdomain / ] DNS 1123 label
