CNV 2.3

How reproducible:

Very

Steps to Reproduce:
1. Add Hyperconverged CNV deployment to Openshift 4.4 cluster from the cnv operator
2. Add Taint to a worker
3. Restart worker

Actual results:

Virt-handler pod will not be schedulable on worker after taint is applied.

Expected results:

Virt-handler pod should have operator exists toleration to run on tainted nodes like other system components.

Below is an example from tuned:
