Hi @alimehrabikoshki. Thanks for your PR.

I'm waiting for a kubernetes-sigs 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.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

Could you give more details in the commit message on the reason why we need this ?
I understand this prevent handlers override, but from where exactly ? A link to the underlying ansible issue explaining the mechanism would be also good.
(Basically, someone reading your commit message in two year should have all the context)

Could you make it more explicit than this a workaround to not import handlers ? Change the file name to something like 'none / not_existing /whatever'
