The Istio task: Enabling Rate Limits
We didn't see the expected message "RESOURCE_EXHAUSTED:Quota is exhausted for: requestcount." after applying all the steps in that task doc.
The enabling rate limits function is not working in the following setup:

Build: istio maistra-0.8.0
Environment: OCP 3.11
OCP console: https://tmor2-master.bc.jonqe.lab.eng.bos.redhat.com:8443/console/catalog

Test steps: https://preliminary.istio.io/docs/tasks/policy-enforcement/rate-limiting/
Test scripts: https://gitlab.cee.redhat.com/istio/istio-tasks-test-tools/blob/master/tests/TC_14_Rate_Limiting.sh

Results:
Both Rate limits and Conditional rate limits not working. Bookinfo productpage cannot hit the quota limit after setting the quota limit quota.
