Description of problem:
master are rebooted once a PerformanceProfile is being created for CNF workers
Version-Release number of selected component (if applicable):
4.14.0
Steps to Reproduce:
* Install a compact cluster, 3 masters - 0 worker * Run this command: oc patch Scheduler cluster --type=merge --patch '{ "spec": { "mastersSchedulable": false } }' * The masters should not have the worker role anymore * Create a Performance Profile, with node selector set for workers only, not masters
Actual results:
The masters are rebooted.
Expected results:
The masters are not rebooted; only workers would be rebooted if we had any worker, since the PerformanceProfile would be applied.
