Request: Option to use self signed webhooks when using "make deploy-setup-k8s"

[oshoval]

We are using make deploy-setup-k8s
Until now we used sriov-operator 4.4 and created a self signed CaBundles,
and then patched the 3 webhooks to have the CaBundles:
validatingwebhookconfiguration sriov-operator-webhook-config
mutatingwebhookconfiguration sriov-operator-webhook-config
mutatingwebhookconfiguration network-resources-injector-config
All went fine.

When we tried to use sriov-operator version 4.8, we saw that the CaBundle is removed after a minute or two.
The reason is that it has now a owner which reconcile it
https://github.com/openshift/sriov-network-operator/blob/49045c36efb9136813f049b9977fe2b93c0a46c0/controllers/sriovoperatorconfig_controller.go#L146

Even if we tried to inject the CaBundle to the configmap in the code above,
the configmap as well was reconciled.

It will be great to have please a method that will allow us to use self signed certs on k8s installation,
without the need to disable the webhook.

Thanks
