Migrate tooling off of gs://kubernetes-jenkins

[michelle192837]

Follow-up to the control plane migration (https://github.com/kubernetes/test-infra/issues/33350).

Tools like Kettle, TestGrid, and others read from gs://kubernetes-jenkins, but should switch to using the new bucket (gs://kubernetes-ci-logs) or something else if needed.

• [x] Ensure results from kubernetes-jenkins are synced to kubernetes-ci-logs (believe this is already done as part of the control plane migration?)
• [x] Migrate Kettle
• [x] Migrate TestGrid
• [x] Migrate other miscellaneous use
• [x] K8s Infra Prow writes to kubernetes-ci-logs instead of kubernetes-jenkins
• [ ] Remove access permissions from kubernetes-jenkins
• [ ] Update references to kubernetes-jenkins across repos
  • [ ] kubernetes-sigs / prow
  • [ ] (any others?)
