Hi @ialidzhikov. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Looks like in this PR I wrongly introduced adaptations in the pkg/util/tolerations/tolerations_test.go. This PR should be only for pkg/scheduler. That's why I will revert the changes in pkg/util/tolerations/tolerations_test.go - as because of this it requires approval from pkg/OWNERS and not pkg/scheduler/OWNERS.
