Description of problem: 
virt-template-validator pods are getting scheduled on same nodes on a upgraded cluster 
On Fresh install pods are on different nodes
probably because of node drain during CNV upgrade pods are scheduling on same nodes

[akriti@fedora ~]$ oc describe pod virt-template-validator-6d8c4bbf5b-t27pw -n openshift-cnv | grep Node:
Node:                 cnv-qe-infra-07.cnvqe2.lab.eng.rdu2.redhat.com/10.1.156.7
