Output of grepping failure-domain.beta.kubernetes.io at the top-level perf-tests repo directory, master branch:

./clusterloader2/vendor/k8s.io/api/core/v1/well_known_labels.go:22:	LabelZoneFailureDomain       = "failure-domain.beta.kubernetes.io/zone"

./compare/vendor/k8s.io/apimachinery/pkg/apis/meta/v1/well_known_labels.go:24:	LabelZoneRegion        = "failure-domain.beta.kubernetes.io/region"

Not seeing any references to LabelZoneFailureDomain nor LabelZoneRegion in the non-vendored code.

Fixes #1554.

For some reason prometheus' disk is still using failure-domain.beta.kubernetes.io.zone: kubernetes/kubernetes#96509 (comment)

Before the next attempt to submit this we should make sure that presubmit used by perf-test repo uses --check-leaked-resources (and potential other differences between ci-kubernetes-e2e-gci-gce-scalability and perf-tests and k/k presubmits).

This would block submission of this PR.
