When the customer tried to Destroy the OpenShift cluster on GCP on 4.16, the customer had to manually delete a resource to complete the uninstall process.

The uninstall was hung until the below command was run.
```
gcloud compute backend-services list \
--project "${CLUSTER_PROJECT_ID}" \
--uri | \
xargs -I {} --no-run-if-empty gcloud compute backend-services delete {} \
--project "${CLUSTER_PROJECT_ID}"
```
