Issue: In newer versions, the deployment name has changed from
frr-k8s-webhook-server to frr-k8s-statuscleaner.

To avoid such fixes in the future it is probably worth to consider more robust
implementation independent from hardcoded naming. On the other hand,
with the current implementation we definitely know what Deployment we
need to ensure the setup is ready. Anyway, I consider this as a follow-up and
don't want to break coverage.

Fix in main: https://github.com/RedHatQE/openshift-virtualization-tests/pull/3664

Need to back-port to 4.21 to avoid failures.
